A software package to compute automorphisms of graded algebras


Abstract in English

We present a library autgradalg.lib for the free computer algebra system Singular to compute automorphisms of integral, finitely generated $mathbb{C}$-algebras that are graded pointedly by a finitely generated abelian group. It implements the algorithms developed in Computing automorphisms of Mori dream spaces. We apply the algorithms to Mori dream spaces and investigate the automorphism groups of a series of Fano varieties.
