We describe the context where p-adic numbers were created at the end of the nineteenth century. Next, algebraic and topologic structures were constructed on that set of numbers by K. Hensel. They are the only complete valued extensions of Q, different from R. All non-Archimedean mathematics grew up during the twentieth century where the fields Qp play the role of R. Now, p-adic analysis finds applications in various scientific domains: quantum physic, dynamical systems, computers. The paper insists on the analogies and overall the differences between methods and results obtained in classical and non-Archimedean mathematics.

Birational invariants and A^1-connectedness

January 2010 · Journal für die reine und angewandte Mathematik

Aravind Asok

We study some aspects of the relationship between A^1-homotopy theory and birational geometry. We study the so-called A^1-singular chain complex and zeroth A^1-homology sheaf of smooth algebraic varieties over a field k. We exhibit some ways in which these objects are similar to their counterparts in classical topology and similar to their motivic counterparts (the (Voevodsky) motive and zeroth ... [Show full abstract] Suslin homology sheaf). We show that if k is infinite the zeroth A^1-homology sheaf is a birational invariant of smooth proper varieties, and we explain how these sheaves control various cohomological invariants, e.g., unramified \'etale cohomology. In particular, we deduce a number of vanishing results for cohomology of A^1-connected varieties. Finally, we give a partial converse to these vanishing statements by giving a characterization of A^1-connectedness by means of vanishing of unramified invariants.

Some means of convex bodies

February 1967 · Transactions of the American Mathematical Society

W. J. Firey

The systematic study of various mean-values of nonnegative valued functions is due in large part to the work of J. L. W. V. Jensen [12], A. Kolmogoroff [11], and B. Jessen [13]. In this paper we present a similar theory of certain means of functions whose values are taken from a collection of convex bodies in a finite dimensional Euclidean space. The range of nonnegative valued functions is ... [Show full abstract] totally ordered while the collection of convex bodies to be considered is partially ordered by set inclusion; corresponding to inequalities, we shall have inclusions, here to be called inequalities, between mean-values. Thus the discussion will furnish an example of a partially ordered system whose algebraic and topological structure is sufficient to admit a fairly elaborate theory of inequalities analogous to that of the real numbers. The first section is a resume of those parts of the work of Jensen, Kolmogoroff, and Jessen for which analogues will be developed. ?2 treats of pertinent material about star and convex bodies. Certain families of star bodies and of convex bodies are defined in the third section; these latter play the role of nonnegative valued functions. Two systems of power means of such families are described. Each system is, in its way, anialogous to the power means of nonnegative valued functions. In ?4 we discuss some special cases of power means including elementary means and the Riemaiin-Minkowski integrals of A. Dinghas [2], [3]. Also some rotation invariants of a convex body are described as power means of special families determined by the convex body. The fifth section begins with crucial properties of the means and contains an extremal characterization for the two systems of means defined in the third section. Analogues of Jensen's and Jessen's inequalities make up ?6. We also mentioni the limiting cases of power means as the power index becomes infinite, positively and negatively. As an applicationl of Jessen's inequality, a Brunn-Minkowski type theorem is proved. In the final section we discuss some further systems of meanls of convex bodies. 1. The definition of the elementary power means extends in a natural way to include power means of certain functions f which have finite, nonnegative values and whose domain T is a compact topological group equipped with its Haar measure. Iff is bounded and measurable over its domain, its pth- power mean is defined by

A functorial formalism for quasi-coherent sheaves on a geometric stack

April 2013 · Expositiones Mathematicae

A geometric stack is a quasi-compact and semi-separated algebraic stack. We prove that the quasi-coherent sheaves on the small flat topology, Cartesian presheaves on the underlying category, and comodules over a Hopf algebroid associated to a presentation of a geometric stack are equivalent categories. As a consequence, we show that the category of quasi-coherent sheaves on a geometric stack is a ... [Show full abstract] Grothendieck category. We associate, in a 2-functorial way, to a 1-morphism of geometric stacks f, an adjunction (f^*, f_*) for the corresponding categories of quasi-coherent sheaves that agrees with the classical one defined for schemes. This construction is described both geometrically in terms of the small flat site and algebraically in terms of the Hopf algebroid.

Bezout-type Theorems for Differential Fields

January 2015 · Compositio Mathematica

Gal Binyamini

We prove analogs of the Bezout and the Bernstein-Kushnirenko-Khovanskii theorems for systems of algebraic differential conditions over differentially closed fields. Namely, given a system of algebraic conditions on the first $l$ derivatives of an $n$-tuple of functions, which admits finitely many solutions, we show that the number of solutions is bounded by an appropriate constant (depending ... [Show full abstract] singly-exponentially on $n$ and $l$) times the volume of the Newton polytope of the set of conditions. This improves a doubly-exponential estimate due to Hrushovski and Pillay. We illustrate the application of our estimates in two diophantine contexts: to counting transcendental lattice points on algebraic subvarieties of semi-abelian varieties, following Hrushovski and Pillay; and to counting the number of intersections between isogeny classes of elliptic curves and algebraic varieties, following Freitag and Scanlon. In both cases we obtain bounds which are singly-exponential (improving the known doubly-exponential bounds) and which exhibit the natural asymptotic growth with respect to the degrees of the equations involved.

Examples of Dynamical Degree Equals Arithmetic Degree

December 2012 · The Michigan Mathematical Journal

Let f : X --> X be a dominant rational map of a projective variety defined over a number field. An important geometric-dynamical invariant of f is its (first) dynamical degree d_f= lim SpecRadius((f^n)^*)^{1/n}. For algebraic points P of X whose forward orbits are well-defined, there is an analogous (upper) arithmetic degree a_f(P) = limsup h_X(f^n(P))^{1/n}, where h_X is an ample Weil height on ... [Show full abstract] X. In an earlier paper, we proved the fundamental inequality a_f(P) \le d_f and conjectured that a_f(P) = d_f whenever the orbit of P is Zariski dense. In this paper we show that the conjecture is true for several types of maps. In other cases, we provide support for the conjecture by proving that there is a Zariski dense set of points with disjoint orbits and satisfying a_f(P) = d_f.

Zamolodchikov integrability via rings of invariants

June 2015

Pavlo Pylyavskyy

Zamolodchikov periodicity is periodicity of certein recursions associated with box products X \square Y of two finite type Dynkin diagrams. We suggest an affine analog of Zamolodchikov periodicity, which we call Zamolodchikov integrability. We conjecture that it holds for products X \square Y, where X is a finite type Dynkin diagram and Y is an extended Dynkin diagram. We prove this conjecture ... [Show full abstract] for the case of A_m \square A_{2n-1}^{(1)}. The proof employs cluster structures in certain classical rings of invariants, previously studied by S.~Fomin and the author.

Evolution integrals

March 2006 · JOURNAL OF OPERATOR THEORY

Rocco Duvenhage

A framework analogous to path integrals in quantum physics is set up for abstract dynamical systems in a W*-algebraic setting. We consider spaces of evolutions, defined in a specific way, of a W*-algebra A as an analogue of spaces of classical paths, and show how integrals over such spaces, which we call ``evolution integrals'', lead to dynamics in a Hilbert space on a ``higher level'' which is ... [Show full abstract] viewed as an analogue of quantum dynamics obtained from path integrals. The measures with respect to which these integrals are performed are projection valued.

On a real analog of Bezout inequality and the number of connected components of sign conditions

March 2013 · Proceedings of the London Mathematical Society

Let $\mathrm{R}$ be a real closed field and $Q_1, \ldots, Q_{\ell} \in \mathrm{R}[X_1, \ldots,X_k]$ such that for each $i, 1 \leq i \leq \ell$, $\deg (Q_i) \leq d_i$. For $1 \leq i \leq \ell$, denote by $\mathcal{Q}_i = \{Q_1, \ldots, Q_i \}$, $V_i$ the real bvariety defined by $\mathcal{Q}_i$, and $k_i$ an upper bound on the real dimension of $V_i$ (by convention $V_0 = ^k$ and $k_0 = k$). ... [Show full abstract] Suppose also that \[ 2 \leq d_1 \leq d_2 \leq \frac{1}{k + 1} d_3 \leq \frac{1}{(k + 1)^2 d_4 \leq \cdots \leq \frac{1}{(k + 1)^{\ell - 3}} d_{\ell - 1} \leq \frac{1}{(k + 1)^{\ell - 2}} d_{\ell}, \] and that $\ell \leq k$. We prove that the number of semi-algebraically connected components of $V_{\ell}$ is bounded by \[ O (k)^{2 k} \left(\prod_{1 \leq j < \ell} d_j^{k_{j - 1} - k_j} \right) d_{\ell}^{k_{\ell - 1}} . \] This bound can be seen as a weak extension of the classical Bezout inequality (which holds only over algebraically closed fields and is provably false over real closed fields) to varieties defined over real closed fields. Additionally, if $\mathcal{P} \subset \mathrm{R}[X_1, \ldots, X_k] \nocomma$ is a finite family of polynomials with $\deg (P) \leq d$ for all $P \in \mathcal{P}$, $\mathrm{card} \mathcal{P}= s$, and $d_{\ell} \leq \frac{1}{k + 1} d_{}$, we prove that the number of semi-algebraically connected components of the realizations of all realizable sign conditions of the family $\mathcal{P}$ restricted to $V_{\ell}$ is bounded by \[ O (k)^{2 k} (s d)^{k_{\ell}} \left(\prod_{1 \leq j \leq \ell} d_j^{k_{j - 1} - k_j} \right) .

Brauer spaces for commutative rings and structured ring spectra

October 2011

Markus Szymik

Using an analogy between the Brauer groups in algebra and the Whitehead groups in topology, we first use methods of algebraic K-theory to give a natural definition of Brauer spectra for commutative rings, such that their homotopy groups are given by the Brauer group, the Picard group and the group of units. Then, in the context of structured ring spectra, the same idea leads to two-fold ... [Show full abstract] non-connected deloopings of the spectra of units.

Some chains of Discrete Event Systems

The study of discrete event systems (DES) has been developed as a new computational tool for generating formal languages. Following the logical model of Ramadge and Wonham, an algebraic structure of some chains of DES, by considering them as dynamical systems, can be constructed. To do so, we use the well known equivalence of Nerode, the analogy between classical dynamical systems theory and the ... [Show full abstract] new theory of DES.

The action on cohomology by compositions of rational maps

We use intuitive results from algebraic topology and intersection theory to clarify the pullback action on cohomology by compositions of rational maps. We use these techniques to prove a simple sufficient criterion for functoriality of a composition of two rational maps on all degrees of cohomology and we then reprove the criteria of Diller-Favre, Bedford-Kim, and Dinh-Sibony. We conclude with a ... [Show full abstract] cautionary example.
