The talk Localization of $W^{-1,q}$ norm for local a posteriori efficiency, by Jan Blechta, will be held on Monday April 4, 2016 at 9:00 in room K6. Abstract We show how to localize dual norms of bounded linear functionals on the Sobolev space $W_0^{1,p}(\Omega)$. The only condition is that the functional in question vanishes over locally supported test functions from $W_0^{1,p}(\Omega)$ which ...

The talk Adaptive inexact Newton methods, by Martin Vohralík (INRIA de Paris), will be held on Monday March 21, 2016 at 9:00 in room K6. Abstract We describe in this lecture an adaptive inexact Newton method. Herein, to solve a nonlinear algebraic system arising from a numerical discretization of a steady nonlinear partial differential equation, we consider ...

The talk Polynomial-degree-robust a posteriori estimates in a unified setting, by Martin Vohralík (INRIA de Paris), will be held on Monday March 7, 2016 at 9:00 in room K6. Abstract We present equilibrated flux a posteriori error estimates in a unified setting for conforming, nonconforming, discontinuous Galerkin, and mixed finite element discretizations of the two-dimensional Poisson problem. ...

The talk On a Parabolic-Hyperbolic Filter for Image Processing, by Michael Pokojovy (Charles University in Prague), will be held on Monday February 29, 2016 at 9:00 in room K6. Abstract We propose a novel PDE-based anisotropic filter for multicolor image denoising. Our filter can be viewed as a hyperbolic relaxation of the well-known parabolic Perona & Malik ...

Title: Preconditioned iterative methods for the least squares problem - Part II Abstract: The talk will represent an introduction to the linear least squares tackled by iterative ...

The talk Preconditioned iterative methods for the least squares problem, by Miroslav Tůma, will be held on Monday November 23, 2015 at 9:00 in room K3. Abstract The talk will represent an introduction to the linear least squares tackled by iterative methods. Basic solution approaches will be mentioned and one particular way to solve the problem ...

The talk Existence, uniqueness and optimal regularity results for very weak solutions to nonlinear elliptic systems, by Sebastian Schwarzacher, will be held on Monday November 2nd, 2015 at 9:00 in room K3. Abstract We establish existence, uniqueness and optimal regularity results for very weak solutions to certain nonlinear elliptic boundary value problems. We introduce structural asymptotic assumptions of ...

The talk Computational study on flows of fluids characterized by non-monotone implicit constitutive relations, by Giordano Tierra, will be held on Monday October 26, 2015 at 9:00 in room K3. Abstract In this talk we present a computational study on unsteady flows of a class of non-Newtonian incompressible fluids characterized by non-monotone constitutive relations relating the symmetric part ...
