ABSTRACT: It has been shown by Claire Voisin in 2003 that one cannot always deform a compact Kähler manifold into a projective algebraic manifold, thereby answering negatively a question raised by Kodaira. In this article, we prove that under an additional semipositivity or seminegativity condition on the canonical bundle, the answer becomes positive, namely such a compact Kähler manifold can be approximated by deformations of projective manifolds.Mathematische Annalen 01/2015;  [Show abstract] [Hide abstract]
ABSTRACT: Let \(X\) be a Stein manifold of complex dimension at least two, \(F:X \rightarrow {{\mathbb {C}}}^n\) a local biholomorphism, and \(q\in F(X)\) . In this paper we formulate sufficient conditions, involving only objects naturally associated to \(q\) , in order for the fiber over \(q\) to be finite. Assume that \(F^{1}(l)\) is \(1\) connected for the generic complex line \(l\) containing \(q\) , and \(F^{1}(l)\) has finitely many components whenever \(l\) is an exceptional line through \(q\) . Using arguments from topology and differential geometry, we establish a sharp estimate on the size of \(F^{1}(q)\) . It follows that for \(n\ge 2\) a local biholomorphism of \(X\) onto \({{\mathbb {C}}}^n\) is invertible if and only if the pullback of every complex line is \(1\) connected.Mathematische Annalen 12/2014;

ABSTRACT: We study smooth hypersurfaces of degree \(d\ge n+1\) in \(\mathbf{P}^n\) whose spaces of smooth rational curves of low degrees are larger than expected, and show that under certain conditions, the primitive part of the middle cohomology of such hypersurfaces have nontrivial Hodge substructures. As an application, we prove that the space of lines on any smooth Fano hypersurface of degree \(d \le 8\) in \(\mathbf{P}^n\) has the expected dimension \(2nd3\) .Mathematische Annalen 12/2014; 360(34).

ABSTRACT: Let $K=\mathbb{Z}/p \ \mathbb{Z}$ and let $A$ be a subset of $\GL_r(K)$ such that $\langle A \rangle$ is solvable. We reduce the study of the growth of $A$ under the group operation to the nilpotent setting. Specifically we prove that either $A$ grows rapidly (meaning $A\cdot A\cdot A\gg A^{1+\delta}$), or else there are groups $U_R$ and $S$, with $S/U_R$ nilpotent such that $A_k\cap S$ is large and $U_R\subseteq A_k$, where $k$ is a bounded integer and $A_k = \{x_1 x_2 \dotsb x_k : x_i \in A \cup A^{1} \cup \{1\}\}$. The implied constants depend only on the rank $r$ of $\GL_r(K)$. When combined with recent work by Pyber and Szab\'o, the main result of this paper implies that it is possible to draw the same conclusions without supposing that $\langle A \rangle$ is solvable. It is our intention to extend the main result of this paper to hold for $\GL_r(\mathbb{F}_q)$, $q$ an arbitrary prime power.Mathematische Annalen 10/2014; 360(12):157208.

ABSTRACT: Let k be a number field and F a function field in one variable over k. We prove that the ramification of a \(p\) torsion element in \(Br\) ( \(F\) ) on a regular proper model over the ring of integers in \(k\) can be split in an extension of degree \(p^3\) . Using this result, we show that ColliotThélène’s conjecture on 0cycles of degree 1 implies finiteness for the \(u\) invariant of the function field of a curve over a totally imaginary number field and periodindex bounds for the Brauer groups of arbitrary fields of transcendence degree 1 over the rational numbers.Mathematische Annalen 10/2014; 360(12).

ABSTRACT: We prove that on closed Riemannian manifolds with infinite abelian, but not cyclic, fundamental group, any isometry that is homotopic to the identity possesses infinitely many invariant geodesics. We conjecture that the result remains true if the fundamental group is infinite cyclic. We also formulate a generalization of the isometryinvariant geodesics problem, and a generalization of the celebrated Weinstein conjecture: on a closed contact manifold with a selected contact form, any strict contactomorphism that is contactisotopic to the identity possesses an invariant Reeb orbit.Mathematische Annalen 09/2014; 
Article: A Twisted Motohashi Formula and WeylSubconvexity for $L$functions of Weight Two Cusp Forms
[Show abstract] [Hide abstract]
ABSTRACT: We derive a Motohashitype formula for the cubic moment of central values of $L$functions of level $q$ cusp forms twisted by quadratic characters of conductor $q$, previously studied by Conrey and Iwaniec and Young. Corollaries of this formula include Weylsubconvex bounds for $L$functions of weight two cusp forms twisted by quadratic characters, and estimates towards the RamanujanPetersson conjecture for Fourier coefficients of weight 3/2 cusp forms.Mathematische Annalen 09/2014;
