Module-valued ordinary differential equations and structure of solution spaces

Abstract

We define and study ordinary differential equations (ODEs) for functions valued in a Banach module $V$ over a finite-dimensional $\mathbb{k}$-algebra $\Lambda$ by using the tensor of Banach modules. Furthermore, we show that the solution space of a homogeneous linear ODE as above is shown to be a finitely generated $\Lambda$-submodule.
