19 p, 335.6 KB Existence of principal values of some singular integrals on Cantor sets, and Hausdorff dimension / Cufí Sobregrau, Julià, 1945- (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Donaire Benito, Juan Jesús (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Mattila, Pertti (University of Helsinki. Department of Mathematics and Statistics) ; Verdera, Joan (Centre de Recerca Matemàtica)
Consider a standard Cantor set in the plane of Hausdorff dimension 1. If the linear density of the associated measure µ vanishes, then the set of points where the principal value of the Cauchy singular integral of µ exists has Hausdorff dimension 1. [...]

29 p, 474.6 KB On restricted weak-type constants of Fourier multipliers / Osekowski, Adam (University of Warsaw. Department of Mathematics, Informatics and Mechanics)
We exhibit a large class of symbols m: Rd ! C for which the corresponding Fourier multipliers Tm satisfy the following restricted weak-type estimates: if A Rd has finite Lebesgue measure, then. . . In particular, this leads to novel sharp estimates for the real and imaginary part of the Beurling-Ahlfors operator on C. [...]

23 p, 200.1 KB Survival analysis with coarsely observed covariates / Feodor Nielsen, Soren (University of Copenhagen)
In this paper we consider analysis of survival data with incomplete covariate information. We model the incomplete covariates as a random coarsening of the complete covariate, and an overview of the theory of coarsening at random is given. [...]

19 p, 191.4 KB Extrapolation and sharp norm estimates for classical operators on weighted Lebesgue spaces / Dragicevic, Oliver ; Grafakos, Loukas ; Pereyra, María Cristina ; Petermichl, Stefanie
We obtain sharp weighted Lp estimates in the Rubio de Francia extrapolation theorem in terms of the Ap characteristic constant of the weight. Precisely, if for a given 1 < r < [infinity] the norm of a sublinear operator on Lr(w) is bounded by a function of the Ar characteristic constant of the weight w, then for p > r it is bounded on Lp(v) by the same increasing function of the Ap characteristic constant of v, and for p < r it is bounded on Lp(v) by the same increasing function of the r-1/p-1 power of the Ap characteristic constant of v.

33 p, 760.3 KB Cadenas de Markov : estudio sobre el problema de la ruina del jugador / Martínez Leon, Marc ; Bardina i Simorra, Xavier, dir. (Universitat Autònoma de Barcelona. Departament de Matemàtiques) ; Universitat Autònoma de Barcelona. Facultat de Ciències
En este estudio se introduce la teoría de las Cadenas de Markov, aplicando como ejemplo práctico de la misma el caso particular de la ruina del jugador. Utilizando además el método de apuesta conocido como La Martingala aplicado en el juego de la ruleta francesa para estudiar como afecta y que resultado se obtiene en el problema dela ruina del jugador.
This study introduce the theory of Markov chains, applying as a practical example ofthis theory, the particular case of Gambler's ruin. Using in addition the betting method of Martingale applying in the game of european roulette to study how aects and which result we get in the problem of Gambler's ruin.
En aquest estudi s'introdueix la teoria de les Cadenes de Markov, aplicant com exemple pràctic de la mateixa el cas particular de la ruïna del jugador. Utilitzant a mes el mètode d'aposta conegut com La Martingala aplicat en el joc de la ruleta francesa per estudiar com afecta i quin resultat obtenim al problema de la ruïna del jugador.
