Abstract
Given commuting -tuples and , , Banach space operators such that the tensor products pair is strict -isometric (resp., , are invertible and is strict -symmetric), there exist integers , and a non-zero scalar , such that , is strict -isometric and is strict -isometric (resp., there exist integers , and a non-zero scalar , such that , is strict -symmetric and is strict -symmetric. However, is strict -isometric (resp., strict -symmetric) for implies only that is -isometric (resp., is -symmetric).
