Tropical bases by regular projections
Abstract
We consider the tropical variety T(I) of a prime ideal I generated by the polynomials f1, ..., fr and revisit the regular projection technique introduced by Bieri and Groves from a computational point of view. In particular, we show that I has a short tropical basis of cardinality at most r + I + 1 at the price of increased degrees, and we provide a computational description of these bases.
