Abrtract. Sufficient conditions are given such that the product T1T2 of two unbounded operators in Hilbert spaces is essentially selfadjoint and that the nonzero numbers in the essential spectrum of the closure of TlT2 coincide with the nonzero numbers in the essential spectrum of T2T1.

In this paper a topology on Hilbert spaces is defined. The continuity of a map with respect to such a topology is equivalent to the untform S-continuity around the origin, according to the Gross definition. An example ofan application, in which the achieved result gives a simple toolfor proving the
