**ABSTRACT:**We show that harmonic functions are not zero divisors in the algebra of real-valued continuous functions on the Sierpinski fractal.Archiv der Mathematik 11/2015; DOI:10.1007/s00013-015-0838-2 - [Show abstract] [Hide abstract]

**ABSTRACT:**In this paper, we use methods from the spectral theory of automorphic forms to give an asymptotic formula with a power saving error term for Andrews’ smallest parts function spt(n). We use this formula to deduce an asymptotic formula with a power saving error term for the number of 2-marked Durfee symbols associated to partitions of n. Our method requires that we count the number of Heegner points of discriminant −D < 0 and level N inside an “expanding” rectangle contained in a fundamental domain for Γ0(N).Archiv der Mathematik 11/2015; 105(6).

**ABSTRACT:**We consider the simultaneous sign change of Fourier coefficients of two modular forms with real Fourier coefficients. In an earlier work, the second author with Sengupta proved that two cusp forms of different (integral) weights with real algebraic Fourier coefficients have infinitely many Fourier coefficients of the same as well as opposite sign, up to the action of a Galois automorphism. In the first part, we strengthen their result by doing away with the dependency on the Galois conjugacy. In fact, we extend their result to cusp forms with arbitrary real Fourier coefficients. Next we consider simultaneous sign change at prime powers of Fourier coefficients of two integral weight Hecke eigenforms which are newforms. Finally, we consider an analogous question for Fourier coefficients of two half-integral weight Hecke eigenforms.Archiv der Mathematik 11/2015; 105(5):413-424.

**ABSTRACT:**It is proved that all subgroups of finite index in a profinite group G are open if and only if G has only countably many abstract maximal subgroups of finite index.Archiv der Mathematik 11/2015; 105(5):401-404. DOI:10.1007/s00013-015-0830-x - [Show abstract] [Hide abstract]

**ABSTRACT:**We show that not all infinite dimensional closed subspaces of ℓ∞ satisfy that the set of their norm-attaining functionals is lineable and prove that any closed subspace of ℓ∞ containing c0 has the property that the set of their norm-attaining functionals is lineable.Archiv der Mathematik 11/2015; 105(5):461-465.

**ABSTRACT:**We prove the following Cantor–Bernstein type theorem, which applies well to the class of symmetric sequence spaces studied earlier by Altshuler, Casazza, and Lin: Let X and Y be Banach spaces having symmetric bases (xn) and (yn), respectively. If each of the bases (xn) and (yn) is equivalent to a basic sequence generated by one vector of the other, then the spaces X and Y are isomorphic. As a consequence, we obtain the strong equivalence that two Lorentz sequence spaces have the same linear dimension if and only if they are isomorphic.Archiv der Mathematik 11/2015; 105(5):425-433.

**ABSTRACT:**Due to the works of Berndt and others (J Reine Angew Math 395:132–141, 1989; Geom Dedicata 138:129–150, 2009; Trans Am Math Soc 359:3425–3438, 2007), we find that the class of all homogeneous real hypersurfaces M in (Formula presented.) has just one example which is minimal in this space. Furthermore, in this ambient space, a homogeneous real hypersurface M is minimal if and only if it is ruled. This fact implies that it is interesting to study this minimal homogeneous real hypersurface from the viewpoint of the geometry of ruled real hypersurfaces. It is known that the shape operator A of every ruled real hypersurface M is given by the characteristic field ξ and the vector field U. The purpose of this paper is to characterize this minimal homogeneous real hypersurface in (Formula presented.) in the class of all ruled real hypersurfaces M by investigating the first curvature of all integral curves of the vector fields ξ and U. Note that there exist minimal non-homogeneous ruled real hypersurfaces in (Formula presented.) (see Geom Dedicata 79:267–286, 1999; Hokkaido Math J 43:1–14, 2014).Archiv der Mathematik 10/2015; 105(6). DOI:10.1007/s00013-015-0839-1 - [Show abstract] [Hide abstract]

**ABSTRACT:**In Mann (More on normally monomial p-groups, 2015), he proves some bounds on the size of gaps between character degrees of maximal class p-groups. In this note we construct a family of examples that shows that one of these bounds is sharp.Archiv der Mathematik 10/2015; 105(6). DOI:10.1007/s00013-015-0836-4 - [Show abstract] [Hide abstract]

**ABSTRACT:**Let k be a positive integer, and suppose that the number of elements of a group G that are not k th powers in G is nonzero but finite. If G is finite, we obtain an upper bound on |G|, and we present some conditions sufficient to guarantee that G actually is finite.Archiv der Mathematik 10/2015; 105(6).

**ABSTRACT:**For s, x > 0, the lower incomplete gamma function is defined to be the integral (Formula presented.), which can be continued analytically to an open subset of (Formula presented.). Here in this article, we study the transcendence of special values of the lower incomplete gamma function, by means of transcendence of certain infinite series. These series are variants of series which are of great interest in number theory. However, these series are also of independent interest and can be studied in the context of the theory of E-functions.Archiv der Mathematik 10/2015; 105(3):271-283.

**ABSTRACT:**Inspired by the work in Dix and Karakostas (Nonlinear Anal. 71:3872–3880, 2009), we prove in this paper a new fixed point theorem for strict-set contractions leaving invariant a cone in a Banach space. This new result is used to obtain an existence result for Urysohn type integral equations.Archiv der Mathematik 10/2015; 105(4):389-399.

**ABSTRACT:**We discuss a condition on a p-subgroup H of a finite group G that is both more general and easier to work with than the assumption that H is weakly s-permutable in G. Our condition is that (Formula presented.), where U = Op(H), and we assume that this condition holds for every subgroup H of order d that is normal in some fixed Sylow p-subgroup P of G, where d > 1 is a fixed power of p dividing |G|. We show in this situation that either G is p-supersolvable or else (Formula presented.), and we derive some corollaries that extend known results concerning weakly s-permutable subgroups.Archiv der Mathematik 10/2015; 105(3):215-222.

**ABSTRACT:**The paper deals with bounded non-selfadjoint operators having Hilbert–Schmidt imaginary Hermitian components. A perturbation bound for invariant subspaces is established. Our results can be considered as a particular generalization of the well-known Davis–Kahan sin θ-theorem for selfadjoint operators.Archiv der Mathematik 09/2015; 105(5).

**ABSTRACT:**We call a closed basic semialgebraic set X ⊂ Rn homogeneous if it is defined by a finite system of inequalities of the form g(x) ≥ 0, where g is a homogeneous polynomial. We prove an effective version of the Putinar and Vasilescu Positivstellensatz for positive homogeneous polynomials on homogeneous semialgebraic sets.Archiv der Mathematik 09/2015; 105(5).
