Semigroups of Difference Operators in Spectral Analysis of Linear Differential Operators

Functional Analysis and Its Applications, 1996
Let \(U\) denote a family of evolution operators for the equation \(x(t)= A(t)x(t)\), \(t\in\mathbb{R}\), where \(A(t): D(A(t))\subset X\to X\) is a family of closed linear operators that generate a correct Cauchy problem; \(X\) is a complex Banach space.

On Solution Spaces of Products of Linear Differential or Difference Operators

ACM Communications in Computer Algebra, 2015
We consider linear ordinary differential or difference systems of the form L(y) = 0 where L is an operator with matrix coefficients, the unknown vector y has m components y1, . . . , ym, m > 1. The matrix coefficients are of size m x m, their entries belong to a differential or difference field K of characteristic 0.
