Uniqueness of unconditional basis of infinite direct sums of quasi-Banach spaces
Uniqueness of unconditional basis of infinite direct sums of quasi-Banach spaces
Abstract This paper is devoted to providing a unifying approach to the study of the uniqueness of unconditional bases, up to equivalence and permutation, of infinite direct sums of quasi-Banach spaces. Our new approach to this type of problem permits to show that a wide class of vector-valued sequence spaces …
