Michael Wibmer
We present a characterization of differential Picard-Vessiot extensions which is analogous to the field theoretic characterization of Galois extensions in classical Galois theory.

Skolem-Mahler-Lech type theorems and Picard-Vessiot theory
Michael Wibmer
We show that three problems involving linear difference equations with rational function coefficients are essentially equivalent. The first problem is the generalization of the cla…
