It is shown that for any C*-algebra A of operators on a separable Hilbert space H, there is, for each self-adjoint operator x in the strong closure, Ā, of A, a sequence {xn} of self-adjoint operators ...

Given a conjugation C on a separable complex Hilbert space H, a bounded linear operator T on H is said to be C-skew symmetric if CTC = −T*. This paper describes the maps, on the algebra of all bounded ...
