TitleTraversing symmetric polyhedral fans.
Author(s) Anders N. Jensen
TypeBook, Chapter in Book, Conference Proceeding
AbstractWe propose an algorithm for computing the facets of a pure connected polyhedral fan up to symmetry. The fan is represented by an oracle. With suitable implementations of the oracle the same algorithm can be used for computing secondary fans, Gröbner fans, tropical varieties and Minkowski sums up to symmetry. The algorithm has been implemented in the software Gfan.
KeywordsPolyhedral fans, tropical geometry, algorithms, symmetry
