In an earlier work, we proposed a frame-based kernel analysis approach to the problem of recovering erasures from unknown locations. The new approach led to the stability question on recovering a signal from noisy par...

The DGMRES method for solving Drazin-inverse solution of singular linear systems is generally used with restarting. But the restarting often slows down the convergence and DGMRES often stagnates. We show that adding s...

Let E be a Banach space with the cl-norm||·|| in E/{0}, and let S(E) = {e ∈ E: ||e|| = 1}. In this paper, a geometry characteristic for E is presented by using a geometrical construct of S(E). That is,...

Let M be a full Hilbert C*-module over a C*-algebra A, and let End^(.A4) be the algebra of adjointable operators on M. We show that if A is unital and commutative, then every derivation of End*A(M) is an inner ...

In this paper,we characterize a class of quasi-modular maps on Hilbert C~*-modules which map a "rank one" adjointable operator to another rank one operator.
