Multigrid methods for two-player zero-sum stochastic games [PDF]
Numer. Linear Algebra Appl., 19: 313-342, 2012, 2011 We present a fast numerical algorithm for large scale zero-sum stochastic games with perfect information, which combines policy iteration and algebraic multigrid methods. This algorithm can be applied either to a true finite state space zero-sum two player game or to the discretization of an Isaacs equation.

Regularization method and a posteriori error estimates for the two membranes problem
Open MathematicsThis study presents a regularization method for the two membranes problem with non-homogeneous boundary conditions. We establish both convergence results and a priori estimates for this method.

New Demiclosedness Principles for (firmly) nonexpansive operators [PDF]
arXiv, 2011 The demiclosedness principle is one of the key tools in nonlinear analysis and fixed point theory. In this note, this principle is extended and made more flexible by two mutually orthogonal affine subspaces. Versions for finitely many (firmly) nonexpansive operators are presented. As an application, a simple proof of the weak convergence of the Douglas-

Nonsmooth method for constrained optimization [PDF]
arXiv, 2012 We propose an implicit iterative algorithm for an exact penalty method arising from inequality constrained optimization problems. A rapidly convergent fixed point method is developed for a regularized penalty functional. The applicability and feasibility of the proposed method is demonstrated using large scale inequality constrained problems.

Convergence rates for the classical, thin and fractional elliptic obstacle problems [PDF]
, 2014 We review the finite element approximation of the classical obstacle problem in energy and max-norms and derive error estimates for both the solution and the free boundary. On the basis of recent regularity results we present an optimal error analysis for the thin obstacle problem.
