A generalization of Strassen’s Positivstellensatz
Strassen's Positivstellensatz is a powerful but little known theorem on preordered commutative semirings satisfying a boundedness condition similar to Archimedeanicity. It characterizes the relaxed preorder induced by all monotone homomorphisms to R+ in terms of a condition involving large powers. Here, we generalize and strengthen Strassen's result. As a generalization, …
