Unsupervised and Semi-Supervised Learningrator Π. that maps functions from .(curl) into the lowest order Nédélec finite element space ... The method of [5] and its motivation are outlined in Section 2. In particular, we describe briefly their Nédélec space decomposition, which is the basis of the auxiliary space AMG preconditioners.

Preconditioning of Symmetric Interior Penalty Discontinuous Galerkin FEM for Elliptic Problemsat the variable V-cycle provides an optimal preconditioner for the DG system. The piece-wise constant functions do not have approximation property so in order to control the energy growth of the inter-level transfer operator we apply .—cycle MG. Finally, we present a number of numerical experiments that support the theoretical findings.

On the Multiscale Solution of Constrained Minimization Problemsemi-smooth Newton methods, see [11] for the latter. For a nonlinear multigrid method for smooth problems we refer to [10]. We remark that the references given here are far from exhaustive and refer the reader to the references cited therein.

A Domain Decomposition/Nash Equilibrium Methodology for the Solution of Direct and Inverse Problems s has shown to perform well when using adjoint based techniques or evolutionary algorithms for the optimization..The above methodology is applied to the simulation and shape design optimization for flows in nozzles and around aerodynamical shapes.The results of various numerical experiments show the efficiency of the method presented here.

MINISYMPOSIUM 1: Advanced Multigrid Methods for Systems of PDEselliptic problems discretized by the DG (discontinuous Galerkin) method, whereas the second one deals with a new auxiliary space preconditioning method for (semi—)definite time domain Maxwell (.(curl)) problems.

A Multilevel Method for Discontinuous Galerkin Approximation of Three-dimensional Elliptic Problemsce of algebraic problems is generated. These discrete problems can be associated with coarse versions of DG approximations (of the solution to the original variational problem) on a hierarchy of geometrically nested meshes. The presented numerical results demonstrate the potential of this approach.

Domain Decomposition Based H-Matrix Preconditioners for the Skin Problemock-diagonal matrix as a preconditioner in the PCG iteration. It is shown that the new preconditioner is robust with respect to jumps in the coefficients and it requires less storage and computing time than the standard .-Cholesky factorization.
