MATRIX OPERATORS ON FUNCTION-VALUED FUNCTION SPACES

We study spaces of continuous-function-valued functions that have the property that composition with evaluation functionals induce weak* to norm continuous maps to l(p) space (p is an element of (1, infinity)). Versions of Holder's inequality and Riesz representation theorem are proved to hold on these spaces. We prove a version of Dixmier's theorem for spaces of function-valued matrix operators on these spaces, and an analogue of the trace formula for operators on Hilbert spaces. When the function space is taken to be the complex field, the spaces are just the l(p) spaces and the well-known classical theorems follow from our results.
