dc.description.abstract | We show that a von Neumann J-algebra A of type (B) does not contain J-positive (J-negative) operators. J-projections in A are characterized. The class of plus-operators that are simultaneously self-adjoint and J-self-adjoint is described. © 2007 Pleiades Publishing, Inc. | |
