On blowing up the weighted projective plane

Juergen Hausen, Simon Keicher, Antonio Laface

We investigate the blow-up of a weighted projective plane at a general point. We provide criteria and algorithms for testing if the result is a Mori dream surface and we compute th…

Computing GIT-fans with symmetry and the Mori chamber decomposition of $M ˉ_{0, 6}$

Janko Boehm, Simon Keicher, Yue Ren

We propose an algorithm to compute the GIT-fan for torus actions on affine varieties with symmetries. The algorithm combines computational techniques from commutative algebra, conv…

Computing resolutions of quotient singularities

Maria Donten-Bury, Simon Keicher

Let $G \subseteq G L (n)$ be a finite group without pseudo-reflections. We present an algorithm to compute and verify a candidate for the Cox ring of a resolution $X\rightarrow \mathb…
