Gr{\"o}bner bases over polytopal affinoid algebras
Polyhedral affinoid algebras have been introduced by Einsiedler, Kapranov and Lind to connect rigid analytic geometry (analytic geometry over non-archimedean fields) and tropical geometry. In this article, we present a theory of Gr{\"o}bner bases for polytopal affinoid algebras that extends both Caruso et al.'s theory of Gr{\"o}bner bases on Tate algebras and Pauer et al.'s theory of Gr{\"o}bner bases on Laurent polynomials. We provide effective algorithms to compute Gr{\"o}bner bases for both ideals of Laurent polynomials and ideals in polytopal affinoid algebras. Experiments with a Sagemath implementation are provided.
