Toric geometry in polymake

Abstract

We give an overview of the application 'fulton' for toric geometry of the software framework polymake. Using two-dimensional cyclic quotient singularities as our main example, we will show how to create toric varieties and divisors on these. The Singular interface of polymake allows one to go back to the algebraic side in case there is no combinatorial algorithm known yet, in order to develop new conjectures and algorithms.
