On Operator Periodically Correlated Random Fields,ase, where continuity is weakened to locally square summability. It is our aim now to give such a characterization of periodically correlatedness for second order . continuous time parameters infinite variate locally square integrable random fields.

The Structure of some ,*-Algebras Generated by , Idempotents,ns between generators was studied by Popovich, Samoilenko and Turowska. In the paper we prove that if such an algebra A is .-homogeneous then it is trivial. Such an .-homogeneous .*-algebra . is isomorphic to the algebra of all continuous matrix-functions of dimension . over some compact subspace of the plane ℂ.

Commuting Triples of Subnormal Operators and Related Moment Problems,sult ({xc[9]}, {xc[10]}) for simple sequences and D. Păunescu result ({xc[7]}, {xc[8]}) for double sequences. The analogue problem for triple indexed sequences of operators acting on a Hilbert space is also obtained.

-Numerical Radius in Banach Spaces,f the . classes, which can be naturally extended. Then, we give a first study of this concept. Some of the properties given in the Banach case are original, but most of them are a generalization of the Hilbert case, even if the proofs have to be done in completely different ways.

On the Distance between an Operator and an Ideal, two-sided ideal in .(.). If . is a tensor product of normed spaces, endowed with a tensor norm, an estimation is given for the distance of a tensor product operator . Є.(.) to .(.) and it is applied to the study of the quasi-nilpotency of tensor product operators modulo .(.).
