Abstract: In spite of the important applications of real selfadjoint operators and monotone operators, very few papers have dealt in depth with the properties of such operators. In the present paper, we follow A. Rhodius to… read more here.

Abstract: Abstract Let A be an anti-selfadjoint operator on a Hilbert space H with ‖ A ‖ ≤ 1 2 . We give a sufficient and necessary condition for A to be a commutator of a… read more here.
