$L^2$-Theory for nonlocal operators on domains

Abstract

This thesis explores the $L^2$-Theory for nonlocal operators of L\'evy type on bounded domains, as well as their local counterparts. The research was completed at Bielefeld University in Germany and has since garnered significant attention in the field of analysis of nonlocal operators. To enhance its visibility, we believe it is convenient to make it available on arXiv.
