✦ Synopsis

We prove that the characterization of the singular matrices A satisfying (1) dan(AX) = dan(XA) VX can be reduced to that of matrices satisfying (2) dan(AX) = 0 VX, where dan is a Schur function. Some partial results on the characterization of (2) are obtained.

We discuss the properties of generalized Schur functions and investigate conditions for two generalized decomposable symmetric tensors to be equal. The analogue of replacing generalized Schur functions by generalized trace functions is also considered.

In this paper we use the resolvent semigroup associated to a C 0 -semigroup to introduce the vector-valued Stieltjes transform defined by a C 0 -semigroup. We give new results which extend known ones in the case of a scalar generalized Stieltjes transform. We work with the vector-valued Weyl fractio

Let G be a (algebra) semigroup and let H be a real Hilbert space. Let F(G) be a set of all mappings from G into H . In this paper, we ÿrst try to provide a nonlinear ergodic retraction theorem for the mappings from G to H . Moreover, we introduce the notion of asymptotically nonexpansive-type curves

We present a description of a partial ordering of the complex full symmetric group algebra, CSm, via generalized matrix functions, dr(A), defined on the set of all m x m complex matrices A. We show that for f: S,~ --\* C, if dr(A) = 0 for all positive semidefinite Hermitian matrices A, then f = 0. T
