26 p, 409.7 KB Logarithmic Hardy-Littlewood-Sobolev inequality on pseudo-Einstein 3-manifolds and the logarithmic Robin mass / Maalaoui, Ali (Clark University (Worcester, Estats Units d'Amèrica). Department of Mathematics)
Given a three-dimensional pseudo-Einstein CR manifold (M, T1,0M, θ),vwe study the existence of a contact structure conformal to θ for which the logarithmic Hardy-Littlewood-Sobolev (LHLS) inequality holds. [...]

14 p, 440.2 KB Sobolev Embeddings for Fractional Hajłasz-Sobolev Spaces in the Setting of Rearrangement Invariant Spaces / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Ortiz Vargas, Walter Andrés (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We obtain symmetrization inequalities in the context of Fractional Hajłasz-Sobolev spaces in the setting of rearrangement invariant spaces and prove that for a large class of measures our symmetrization inequalities are equivalent to the lower bound of the measure.

17 p, 209.1 KB Sobolev inequalities with variable exponent attaining the values 1 and n / Harjulehto, Petteri (University of Helsinki. Department of Mathematics and Statistics) ; Hästö, Peter (University of Oulu. Department of Mathematical Sciences)
We study Sobolev embeddings in the Sobolev space W1,p(·) (Ω) with variable exponent satisfying 1 6 p(x) 6 n. Since the exponent is allowed to reach the values 1 and n, we need to introduce new techniques, combining weak- and strong-type estimates, and a new variable exponent target space scale which features a space of exponential type integrability instead of L∞ at the upper end.

17 p, 351.7 KB Isoperimetric Hardy type and Poincaré inequalities on metric spaces / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Milman, Mario (Florida Atlantic University. Department of Mathematics)
We give a general construction of manifolds for which Hardy type operators characterize Poincaré inequalities. We also show a class of spaces where this property fails. As an application, we extend recent results of E. [...]
