Connecting Kaporin's condition number and the Bregman log determinant divergence
Andreas A. Bock, Martin S. Andersen
This paper presents some theoretical results relating the Bregman log determinant matrix divergence to Kaporin's condition number. These can be viewed as nearness measures between…

A New Matrix Truncation Method for Improving Approximate Factorisation Preconditioners
Andreas A. Bock, Martin S. Andersen
In this experimental work, we present a general framework based on the Bregman log determinant divergence for preconditioning Hermitian positive definite linear systems. We explore…
