On the strong closure of the simultaneous similarity orbit of a pair of finite rank operators
Extending his previous work [Acta Sci.\ Math.\ 56, No.\,1--2, 169--174 (1992; Zbl 0784.47030)], the author proves a necessary condition for membership in the strong closure of the simultaneous similarity orbit of a pair of finite rank operators.
