Abstract

The solution to systems of moment differential equations of the form zmy=(zA+B)yz\partial_my=(zA+B)y are provided, for a matrix BB with general good spectrum. Existence and convergence of Floquet-type solutions is studied. A generalized definition of zBz^B is given, as a tool to solve the main problem whenever A0A\equiv 0. The theory is illustrated with examples which are important in applications.
