34 p, 446.8 KB Entire solutions for critical p-fractional Hardy Schrodinger Kirchhoff equations / Piersanti, Paolo (City University of Hong Kong. Department of Mathematics) ; Pucci, Patrizia (Università degli Studi di Perugia. Dipartimento di Matematica e Informatica)
Existence theorems of nonnegative entire solutions of stationary critical p-fractional Hardy Schr¨odinger Kirchhoff equations are presented in this paper. The equations we treat deal with Hardy terms and critical nonlinearities and the main theorems extend several recent results on the topic. [...]

18 p, 358.0 KB On relations between weak and strong type inequalities for maximal operators on non-doubling metric measure spaces / Kosz, Dariusz (Wroclaw University of Science and Technology (Polònia). Faculty of Pure and Applied Mathematics)
In this article we characterize all possible cases that may occur in the relations between the sets of p for which weak type (p, p) and strong type (p, p) inequalities for the Hardy–Littlewood maximal operators, both centered and non-centered, hold in the context of general metric measure spaces.

We introduce a version of Farber's topological complexity suitable for investigating mechanical systems whose configuration spaces exhibit symmetries. Our invariant has vastly different properties to the previous approaches of Colman–Grant, Dranishnikov, and Lubawski–Marzantowicz. [...]

20 p, 392.3 KB Weighted square function inequalities / Osekowski, Adam (University of Warsaw (Polònia). Department of Mathematics, Informatics and Mechanics)
For an integrable function f on [0, 1)d, let S(f) and M f denote the corresponding dyadic square function and the dyadic maximal function of f, respectively. The paper contains the proofs of the following statements. [...]

17 p, 359.4 KB Stability of generalized linear Weingarten hypersurfaces immersed in the Euclidean space / da Silva, Jonatan F. (Universidade Federal do Ceará (Brasil). Departamento de Matemática) ; de Lima, Henrique F. (Universidade Federal de Campina Grande. Departamento de Matemática) ; Velásquez, Marco Antonio L. (Universidade Federal de Campina Grande. Departamento de Matemática)
Given a positive function F defined on the unit Euclidean sphere and satisfying a suitable convexity condition, we consider, for hypersurfaces Mn immersed in the Euclidean space Rn+1, the so-called k-th anisotropic mean curvatures HF k, 0 ≤ k ≤ n. [...]

19 p, 446.4 KB On Poincaré–Bendixson theorem and non-trivial minimal sets in planar nonsmooth vector fields / Buzzi, Claudio Aguinaldo (Universidade Estadual Paulista(Brazil). Departamento de Matemática) ; de Carvalho, Tiago (Universidade Estadual Paulista(Brazil). Departamento de Matemática) ; Euzébio, Rodrigo D. (Universidade Estadual Paulista (Brasil). Departamento de Matemática)
In this paper some qualitative and geometric aspects of nonsmooth vector fields theory are discussed. A Poincaré–Bendixson Theorem for a class of nonsmooth systems is presented. In addition, a minimal set in planar Filippov systems not predicted in classical Poincaré–Bendixson theory and whose interior is non-empty is exhibited. [...]

16 p, 424.3 KB Tangents, rectifiability, and corkscrew domains / Azzam, Jonas (University of Edinburgh. School of Mathematics)
In a recent paper, Csörnyei and Wilson prove that curves in Euclidean space of σ-finite length have tangents on a set of positive H 1-measure. They also show that a higher dimensional analogue of this result is not possible without some additional assumptions. [...]

Departamento de Matemáticas) ; Rodríguez García, Jose M. (Universidad Carlos III de Madrid. Departamento de Matemáticas) ; Tourís, Eva (Universidad Autónoma de Madrid. Departamento de Matemáticas)
In this paper we prove that for every complete n-dimensional Riemannian manifold without Green's function and with its sectional curvatures satisfying K ≤−1, the exponent of convergence is greater than or equal to n − 1. [...]

27 p, 398.3 KB A trace theorem for Besov functions in spaces of homogeneous type / Marcos, Miguel Andrés (Consejo Nacional de Investigaciones Científicas y Técnicas - CONICET (Argentina))
The aim of this paper is to prove a trace theorem for Besov functions in the metric setting, generalizing a known result from A. Jonsson and H. Wallin in the Euclidean case. We show that the trace of a Besov space defined in a 'big set' X is another Besov space defined in the 'small set' F ⊂ X. [...]

39 p, 494.2 KB The Dirichlet problem for nonlocal Lévy-type operators / Rutkowski, Artur (Wroclaw University of Science and Technology (Wroclaw, Polònia). Faculty of Pure and Applied Mathematics)
We present the theory of the Dirichlet problem for nonlocal operators which are the generators of general pure-jump symmetric Lévy processes whose Lévy measures need not be absolutely continuous. We establish basic facts about the Sobolev spaces for such operators, in particular we prove the existence and uniqueness of weak solutions. [...]

32 p, 419.6 KB Strong inner inverses in endomorphism rings of vector spaces / Bergman, George M. (University of California)
For V a vector space over a field, or more generally, over a division ring, it is well-known that every x ∈ End(V ) has an inner inverse; that is, that there exists y ∈ End(V ) satisfying xyx = x. [...]

By means of the modified Abel lemma on summation by parts, we investigate infinite series involving quadratic and cubic harmonic numbers. Several infinite series identities are established for π 2 and ζ(3) as consequences.
