Abstract

This work extends the theory of Samuel numbers to semimodules by introducing a generalized number, $wbar_phi(theta)$ for two axe-filtrations. We establish its existence under regularity conditions, including the Approximable by Powers (AP) and weakly good properties. By adapting the concept of valuative reduction, we prove that this invariant is well-defined and robust, laying the foundation for a quantitative analysis of filtration structures on semimodules.
