Coercivity estimates for integro-differential operators
Jamil Chaker, Luis Silvestre
We provide a general condition on the kernel of an integro-differential operator so that its associated quadratic form satisfies a coercivity estimate with respect to the -sem…

Nonlocal operators with singular anisotropic kernels
Jamil Chaker, Moritz Kassmann
We study nonlocal operators acting on functions in the Euclidean space. The operators under consideration generate anisotropic jump processes, e.g., a jump process that behaves lik…
