Convergence analysis of Schwarz-like methods for degenerate elliptic-parabolic equations Monika Eisenmann · Eskil Hansen May 4, 2026 Abstract Convergence is proven for Schwarz-like methods applied to degenerate elliptic-parabolic equations with a p-structure. This family of PDEs, e.g., arises when modelling nonlinear diffusion processes. The Schwarz-like approximation methods are based on decompos

Transmission problems and domain decompositions for non-autonomous parabolic equations on evolving domains Amal Alphonse, Ana Djurdjevac, Emil Engström, and Eskil Hansen Abstract. Parabolic equations on evolving domains model a multitude of applications including various industrial processes such as the molding of heated materials. Such equations are numerically challenging as they require large-s

Convergence analysis of a full discretization of operator-valued differential Riccati equations Eskil Hansen Tony Stillfjord Teodor Åberg April 28, 2026 Abstract In recent previous work [E. Hansen, T. Stillfjord and T. Åberg, SIAM J. Numer. Anal., to appear], we analyzed the convergence of operator splitting methods applied to operator-valued differential Riccati equations (DRE). In this paper,

Continuous analysis of waveform relaxation for heterogeneous heat equations Philipp Birken[0000−0002−6706−3634] and Martin J. Gander[0000−0001−8450−9223] and Niklas Kotarsky[0009−0001−5135−3776] 1 Introduction We consider the coupling of time dependent partial differential equations (PDEs) across an interface. This can be used to describe the exchange of heat or of forces be- tween different domai

XXXX, 1–39 © De Gruyter YYYY Numerical Methods for Unsteady Thermal Fluid Structure Interaction Philipp Birken and Azahar Monge Abstract. We discuss thermal fluid structure interaction processes, where a simulation of the time dependent temperature field is of interest. Thereby, we consider partitioned coupling schemes with a Dirichlet-Neumann method. We present an analysis of the method on a mode
