Operator-Valued frame generators for group-like unitary systems
Bin Meng
In this paper, we investigate operator-valued frames with the structure of group-like unitary system. We show the commutant of the group-like unitary system can be characterized in…

Finite Operator-Valued Frames
Bin Meng
Operator-valued frames are natural generalization of frames that have been used in quantum computing, packets encoding, etc. In this paper, we focus on developing the theory about…

DGMRES method augmented with eigenvectors for computing the Drazin-inverse solution of singular linear systems
Bin Meng
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 o…
