A natural L ∞ functional calculus for an absolutely continuous contraction is investigated. It is harmonic in the sense that for such a contraction and any bounded measurable function φ on the circle, the image can rightly be considered asˆφ(T), wherê φ is the solution of the Dirichlet problem for the disk with boundary values φ. The main result shows that… (More)

Subnormal operators arise naturally in complex function theory , differential geometry, potential theory, and approximation theory, and their study has rich applications in many areas of applied sciences as well as in pure mathematics. We discuss here some research problems concerning the structure of such operators: subnormal operators with finite-rank… (More)

This paper is a contribution to the problem of approximating continuous functions F defined on a compact HausdorfF space X, where the value F(x) is a compact convex set in R" for every x in X. More specifically we show how to transfer Korovkin type approximation theorems for real-valued continuous functions to this set-valued situation. 1. Introduction. We… (More)

A version of a theorem commonly referred to as Caristi's Theorem is given. It has an elementary constructive proof and it includes many generalizations of Banach's fixed point theorem. Several examples illustrate the diversity that can occur. X is a complete metric space and 4> is lower semicontinuous. If for each x in X, (C) d(x,Tx) <(p(x)-4>(Tx), then T… (More)

Suppose A is a C*-algebra and B is a Banach algebra such that it can be continuously imbedded in B(H), the Banach algebra of bounded linear operators on some Hubert space H. It is shown that if 6 is a compact algebra homomorphism from A into B, then 6 is a finite rank operator, and the range of 0 is spanned by a finite number of idempotents. If, moreover, B… (More)

There exists a large number of elementary books on complex function theory because the subject is taught at all universities and engineering schools. In addition there are many research monographs treating selected topics from complex analysis. The present list is only a small selection in addition to the 3 books mentioned in the introduction.
