Abstract: We completely characterize compact weighted composition operators between $$L^p$$-spaces. The relations among compactness, completely continuity, weakly compactness and M-weakly compactness of these operators are also investigated. read more here.

Abstract: Abstract In this paper, we introduce a new kind of flatness, namely “jumping flatness,” of a Hamburger-type weighted shift; we characterize jumping flatness of a nonsubnormal Hamburger-type weighted shift W α and obtain the expression… read more here.
