In this paper we will obtain a Stone type theorem under the frame of Hilbert C*-module, such that the classical Stone theorem is our special case. Then we use it as a main tool to obtain a spectrum decomposition theo...

Using known Ca-multiplier result, we give necessary and sufficient conditions for the second order delay equations:u″(t)=Au(t)+Fut+Gu′+f(t),t∈Rto have maximal regularity in HSlder continuous function spac...

In this paper we obtain a Douglas type factor decomposition theorem about certain important bounded module maps. Thus, we come to the discussion of the topological continuity of bounded generalized inverse module maps...

A∈B(H) is called Drazin invertible if A has finite ascent and descent. Let σD (A)={λ∈ C : A -λI is not Drazin invertible } be the Drazin .spectrum. This paper shows that if Mc =(A C 0 B)is a 2 × 2 upper t...

We give a simpler proof of a result on operator-valued Fourier multipliers on Lp([0, 2π]d; X) using an induction argument based on a known result when d= 1.
