Bemerkungen über Tensorprodukte koerzitiver Hilbertraum-Operatoren. (Notes on tensor products of coercive Hilbert space operators). (German) Zbl 0678.47019
The problem is considered whether tensor products of coercive operators on Hilbert spaces with respect to the Hilbert space tensor product are coercive again. The answer is no, in general - a counterexample is presented $$-,$$ but yes for the subclass of so-called V-elliptic symmetric operators.
