The problems of approximating linear operators in the 2-induced norm which are (1) finite-dimensional, unstructured, and (2) infinite-dimensional structured (Hankel), have been solved. The solutions of these two problems exhibit striking similarities. These similarities suggest the search of a ur@ji
There are constructed representations of unbounded operator algebras which generalize representations of B ( H ) constructed by J. W. CALKIN and H. BEHNCKE. For a large class of unitary spaces D, each uniformly closed two-sided ideal of the maximal Op\*-algebra L + ( D ) appears as kernel of such a
