Several conditions for the separability in Banach-valued L (p) -spaces are given. Sharp estimates for the resolvent of the corresponding differential operator are obtained. In particular, the sectoriality of this operator is established. As applications, the boundary value problems for degenerate quasielliptic partial differential equations and infinite systems of differential equations on cylindrical domain are studied.eninfo:eu-repo/semantics/closedAccessboundary value problemsseparable boundary value problemsdifferential-operator equationsBanach-valued function spacesoperator-valued multipliersinterpolation of Banach spacessemigroup of operatorsArticleQ2Q21231-26589WOS:00026501770000514
