A note on compactness of tensor products
Main Article Content
Abstract
Compactness is preserved from a pair of operators to their tensor product. The converse was considered in [10] under some restrictions on the spectra of the operators. This paper shows that no restriction is necessary: the converse holds whenever the tensor product is nonzero.
