In this paper, we study the extension properties of a bounded linear transformation from a subspace of a Hilbert space into the whole space (e.g., which has a normal extension). Given an n Γ n normal matrix A and a k Γ n matrix B, k n, we obtain some sufficient conditions of subnormality for the sub
A constructive method for producing a test function space and hence a generalized function space suitable for a given normal operator is developed. Spectral theory and a functional calculus are shown to be valid in these spaces. Application of the theory is illustrated by considering a normal realis
