Optimal relaxation to a planar interface in the Mullins-Sekerka problem
Olga Chugreeva, Felix Otto, Maria G. Westdickenberg
We analyze the convergence rates to a planar interface in the Mullins-Sekerka model by applying a relaxation method based on relationships among distance, energy, and dissipation.…

Strong solvability of regularized stochastic Landau-Lifshitz-Gilbert equation
Olga Chugreeva, Christof Melcher
We examine a stochastic Landau-Lifshitz-Gilbert equation based on an exchange energy functional containing second-order derivatives of the unknown field. Such regularizations are f…
