Parabolic problems for direction-dependent local-nonlocal operators
Jamil Chaker, Moritz Kassmann, Marvin Weidner
We study parabolic equations governed by integro-differential operators with nonlocal components in some directions and local components in the remaining directions. The setting co…
Heat kernel bounds for nonlocal operators with singular kernels
Moritz Kassmann, Kyung-Youn Kim, Takashi Kumagai
We prove sharp two-sided bounds of the fundamental solution for an integro-differential operator of order that generates a -dimensional Markov process. The correspo…
Mosco convergence of nonlocal to local quadratic forms
Guy Fabrice Foghem Gounoue, Moritz Kassmann, Paul Voigt
We study sequences of nonlocal quadratic forms and function spaces that are related to Markov jump processes in bounded domains with a Lipschitz boundary. Our aim is to show the co…
