• Adding user interactivity to FreeFem++ with EJS: From teaching to research 

      Chacón Vera, Eliseo (2015-05-15)
      In this talk we propose the use of an authoring tool, Easy Java Simulations, to build interactive simulations for pdes where the computing kernel is FreeFem++. This tool allows to play with all the parameters of the pde ...
    • Composition of Haar Paraproducts 

      Wick, Brett (2014-12-03)
      Paraproducts are important operators in harmonic analysis and there are well known characterizations of when an individual paraproduct is bounded. An interesting question is to characterize when the composition of two, ...
    • Dominación sparse para conmutadores y estimaciones cuantitativas 

      Rivera Ríos, Israel P. (2018-02-07)
      Dada una funci ́on localmente integrable y un operador lineal T definimos el commutator [b, T ] como [b, T ]f (x) = b(x)T f (x) − T (bf )(x). En esta charla presentaremos resultados de dominación sparse para conmutadores ...
    • On a general metric condition in fixed point theory 

      Adrian, Petrusel (2022-04-25)
      The purpose of this talk is to present some new fixed point results for singlevalued and multivalued orbital (graph) contractions in complete metric spaces. We will consider existence results, as well as some stability ...
    • Optimalidad en la conjetura débil de Muckenhoupt-Wheeden 

      Ombrosi, Sheldy J. (2018-03-06)
      En el año 2009 conjuntamente con A. Lerner y C. P\'erez probamos que la dependencia en relación a la constante $[w]_A_1$ de un peso $w$ en el tipo débil (1,1) de la cualquier operador de Calderón-Zygmund se puede controlar ...
    • Reduction of complexity and variational data assimilation 

      Maday, Yvon (2015-05-15)
      Reduced basis methods belong to a class of approaches of \emph{model reduction} for the approximation of the solution of mathematical models involved in many fields of research or decision making and in data assimilation. ...
    • Resultados de extrapolación y desigualdades con pesos entre espacios de Lebesgue y Lipschitz integrales 

      Cabral, Enrique Adrián (2015-06-10)
      En esta charla se dan resultados de extrapolación partiendo de hipótesis que contienen desigualdades en norma entre espacios de Lebesgue y Lipschitz integrales con pesos. Mediante técnicas de extrapolación, se ...
    • Sawyer’s problem and related open question for one-sided maximal functions 

      Li, Kangwei (2018-03-06)
      In this talk, I will introduce the Sawyer's conjecture, which was proposed by Sawyer in 1980s. Then in 2005, Cruz-Uribe, Martell and Pérez finally solved this conjecture, they also proposed a new conjecture, which can ...
    • The Kolmogorov Law of turbulence: what can rigorously be proved? 

      Lewandowski, Roger (2015-05-15)
      We define a mathematical framework in which we can specify the Reynolds decomposition and the correlation tensors of an incompressible locally homogeneous and isotropic turbulent flow. After having fixed the technical ...
    • Towards general purpose LES model of injection and atomization 

      Hecht, Nicolas (2015-05-15)
      Injection and atomization of liquid is widely used in many industrial and domestic applications such as, fuel injection in engines or burners, spray painting, medical sprays, spray drying, etc. Various approaches are ...
