28 p, 537.8 KB Uniform convergence of {Hankel} transforms / Debernardi Pinos, Alberto (Universitat Autònoma de Barcelona)
We investigate necessary and/or sufficient conditions for the pointwise and uniform convergence of the weighted Hankel transforms [fórmula] where ν, μ ∈ R are such that 0 ≤ μ + ν ≤ α + 3/2. [...]

15 p, 716.4 KB A note on Hurwitz's inequality / Cufí Sobregrau, Julià, 1945- (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Gallego Gómez, Eduardo (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Reventós, Agustí (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
Given a simple closed plane curve Γ of length L enclosing a compact convex set K of area F, Hurwitz found an upper bound for the isoperimetric deficit, namely L2−4πF≤π|Fe|, where Fe is the algebraic area enclosed by the evolute of Γ. [...]

17 p, 416.7 KB Distributional solutions of the Beltrami equation / Baisón Olmo, Antonio L. (Universidad Autónoma Metropolitana - Azcapotzalco (Mèxic). Departamento de Ciencias Básicas (Mexico)) ; Clop, Albert (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Orobitg i Huguet, Joan (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We study the distributional solutions to the (generalized) Beltrami equation under Sobolev assumptions on the Beltrami coefficients. In this setting, we prove that these distributional solutions are true quasiregular maps and they are smoother than expected, that is, they have second order derivatives in Lloc1+ε, for some ε>0.

19 p, 574.3 KB Sharp bounds for composition with quasiconformal mappings in Sobolev spaces / Oliva, Marcos (Universidad Autónoma de Madrid. Departamento de Matemáticas) ; Prats, Martí (Universidad Autónoma de Madrid. Departamento de Matemáticas)
Let φ be a quasiconformal mapping, and let Tφ be the composition operator which maps f to f ˝ φ. Since φ may not be bi-Lipschitz, the composition operator need not map Sobolev spaces to themselves. [...]

17 p, 388.0 KB New Lorentz spaces for the restricted weak-type Hardy's inequalities / Martín i Pedret, Joaquim (Universitat de Barcelona. Departament de Matemàtica Aplicada i Anàlisi) ; Soria, Javier (Universitat de Barcelona. Departament de Matemàtica Aplicada i Anàlisi)
Associated to the class of restricted-weak type weights for the Hardy operator Rp, we find a new class of Lorentz spaces for which the normability property holds. This result is analogous to the characterization given by Sawyer for the classical Lorentz spaces. [...]

22 p, 364.3 KB Entropy function spaces and interpolation / Cerdà Martín, Joan Lluís (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Coll, Heribert (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We associate to every function space, and to every entropy function E, a scale of spaces Λp,q (E) similar to the classical Lorentz spaces Lp,q. Necessary and sufficient conditions for they to be normed spaces are proved, their role in real interpolation theory is analyzed, and a number of applications to functional and interpolation properties of several variants of Lorentz spaces and entropy spaces are given.

27 p, 431.2 KB Symmetrization inequalities in the fractional case and Besov embeddings / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We prove new extended forms of the Pólya-Szegö symmetrization principle in the fractional case. As a consequence we determine new results for rearrangement invariant hulls of generalized Besov spaces.

22 p, 405.8 KB Higher-order symmetrization inequalities and applications / Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Milman, Mario (Florida Atlantic University. Department of Mathematics)
We prove new extended forms of the Pólya-Szegö symmetrization principle. As a consequence new sharp embedding theorems for generalized Sobolev and Besov spaces are proved.

We obtain a Sobolev type embedding result for Besov spaces defined on a doubling measure metric space.

14 p, 519.0 KB Sobolev embedding into BMO and weak-L∞ for 1-dimensional probability measure / Feo, Filomena (Università degli Studi di Napoli Parthenope. Dipartimento di Ingegneria) ; Martín i Pedret, Joaquim (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Posteraro, Maria Rosaria (Universitat Autònoma de Barcelona. Departament de Matemàtiques)
We characterize rearrangement invariant spaces X with respect to a suitable 1-dimensional probability μ (e. g. log-concave measure) such that the Sobolev embedding{norm of matrix}u{norm of matrix}BMO(R,μ)≤C({norm of matrix}u'{norm of matrix}X+{norm of matrix}u{norm of matrix}L1(R,μ)) holds for any function u∈L1(R,μ), whose real-valued weakly derivative u' belongs to X.
