ABSTRACT
Soon after the release of Kato’s paper on strong solutions in Lebesgue spaces, there has been a flourishing of papers on solutions in Morrey spaces: Giga and Miyakawa [175] in 1989, Kato [215] and Taylor [400] in 1992, Federbush [138] in 1993. Those examples have been extended in the books of Cannone [60] in 1995 and Lemarié-Rieusset [267] in 2002, and recently in 2013 in the book of Triebel [409].
