A Note on Complex Interpolation of Quasi-Banach Function Spaces
Moritz Egert, Benjamin W. Kosmala
Kalton and Mitrea characterized complex interpolation spaces of quasi-Banach function spaces as Calderón products if both interpolants are separable. We show that one separability…

A stability result for parabolic measures of operators with singular drifts
Simon Bortz, Moritz Egert, Olli Saari
We study the operator \[ \partial_t - \text{div} A \nabla + B \cdot \nabla \] in parabolic upper-half-space, where is an elliptic matrix satisfying an oscillation condition and…

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…
