Factoring linear differential operators on measure chains.
Finite difference schemes with monotone operators.
Fredholm determinants and the Evans function for difference equations
We develop a difference equations analogue of recent results by F. Gesztesy, K. A. Makarov, and the second author relating the Evans function and Fredholm determinants of operators with semi-separable kernels.
