## Abstract A general procedure is given to get ideals in algebras of unbounded operators starting with ideals in ℬ︁(ℋ︁). Algebraical and topological properties of ideals obtained in this manner from the well‐known symmetrically‐normed ideals S~Ο•~(ℋ︁) are described.

## 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

The closure of the set of finite dimensional operators of a+@) with respect to different topologies is oonaidered. The obtained ideals have many properties similar to those of the idcal of completely continuous operatom on ~E B T space. For example, under some appropriate aesumpt.ione all oontinuous

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 ⍀
