Bounded functional calculus for divergence form operators with dynamical boundary conditions
Tim Böhnlein, Moritz Egert, Joachim Rehberg
We consider divergence form operators with complex coefficients on an open subset of Euclidean space. Boundary conditions in the corresponding parabolic problem are dynamical, that…
