Arithmetic and Polynomials over Fuzzy Rings
Andreas Dress and Walter Wenzel
We study the arithmetic in fuzzy rings and related structures as well as polynomials over these coefficient domains. Fuzzy rings are an appropriate tool for a unified approach to representable, oriented, and valuated matroids. On the other hand, the relatively new field of "Tropical Geometry" as well as "Classical Algebraic Geometry" exhibit several analogies. The methods developed in the present paper will in future research also be fundamental for a unified treatment of these disciplines.
