Ideals in algebras of unbounded operators. I1
By W. TIMMERMANN of Leipzig (Eingegangen am 12. 5. 1978) This paper is part I1 of the investigations begun in [4]. There two classes of ideals in algebras of unbounded operators were defined: So(%) and M(S,(9), SF(9)), where @ is a symmetric norming function [i]. In [4] algebraical and topo- logical properties of 8 , (9) were investigated. Now we indicate some properties of B(S&O), S,( 9)) and show how these ideals are connected with So(%)) by duality properties. All results are taken from [5]. In section 1 we collect some definitions (cf. [l], [el) and results from [4]. Section 2 contains properties of M ( . , .) while section 3 deals with the duality mentioned above.

The purpose of this paper is to study when a weight on an O U -algebra M M on a dense subspace D D in a Hilbert space H H is a trace weighted by a positive self-adjoint operator, that is, when there exists a positive self-adjoint operator β
