The talk On GMRES for singular systems, by Miroslav Rozložník will be held on Monday April 24, 2017 at 9:00 in room K4. Abstract: In this talk we study the numerical behavior of the generalized minimal residual (GMRES) method for solving singular linear systems. GMRES determines a solution without breakdown in theory in the two cases: the coefficient ...

The talk Mixed sparse-dense linear least squares and preconditioned iterative methods, by Miroslav Tůma will be held on Monday April 10, 2017 at 9:00 in room K4. Abstract: The efficient solution of large linear least squares problems in which the system matrix A contains rows with very different densities is challenging. There have been many classical contributions ...

The talk On solving linear systems arising from Shishkin mesh discretizations, by Petr Tichý will be held on Monday April 3, 2017 at 9:00 in room K4. Abstract: We consider a convection-diffusion boundary value problem (1D, convection dominated) with Dirichlet boundary conditions. Because of the occurrence of boundary layers in the solution, such problems are difficult to ...

The talk Multilevel methods and operator preconditioning, by Zdeněk Strakoš will be held on Monday March 27, 2017 at 9:00 in room K4. Abstract: Multilevel adaptive methods represent a very large class of approaches towards solving large scale problems. They can be used either as stand-alone solvers, or as  preconditioning in combination, e.g., with Krylov subspace methods. ...

The talk On analysis of several nonstandard growth problems in fluid and solid mechanics, by Josef Málek will be held on Monday March 20, 2017 at 9:00 in room K4. Abstract: After a brief review of what one can understand as a PDE problem with standard and nonstandard growth, we present several nonstandard growth problems in fluid ...

The talk Gauss quadrature and Lanczos algorithm, by Miroslav Pranic will be held on Monday March 13, 2017 at 9:00 in room K4. Abstract: Gauss quadrature can be naturally generalized to approximate quasi-definite linear functionals, where the interconnections with (formal) orthogonal polynomials, (complex) Jacobi matrices and Lanczos algorithm are analogous to those in the positive definite case. ...

The talk On the role of thermodynamics in the stability analysis of motion of viscoelastic rate type fluids, by Vít Průša will be held on Monday March 6, 2017 at 9:00 in room K4. Abstract: Analysis of the stability of a solution to a system of nonlinear partial differential equations is a quite challenging task. I will ...

The talk Efficient Implementation of Spectral Discontinuous Galerkin methods, by Peter Bastian  (Interdisciplinary Center for Scientific Computing, Heidelberg University) will be held on Monday February 27, 2017 at 9:00 in room K4. Abstract: Unleashing the high-performance advertised by current supercomputers provides quite a challenge for finite element methods. The traditional approach of setting up a stiffness  matrix ...
