"Preconditioning for PDE-constrained optimization"

Optimization problems with constraints in terms of partial differential equations arise in many scientific and engineering applications. Discretization and, in the nonlinear case, linearization of such problems result in (a sequence of) large structured algebraic linear systems in saddle point form. The minisymposium is aimed at providing insights on recent developments with respect to the construction and the analysis of efficient methods for solving these linear systems. The talks will mainly focus on ef´Čücient preconditioning techniques in combination with Krylov subspace methods.
