Classifying log del Pezzo surfaces with torus action
Daniel Haettig, Juergen Hausen, Justus Springer
We consider log del Pezzo surfaces coming with a non-trivial torus action. Such a surface is 1/k-log canonical if it allows a resolution of singularities with discrepanies all grea…

Del Pezzo surfaces of Picard number one admitting a torus action
Daniel Haettig, Beatrice Hafner, Juergen Hausen +1
We present efficient classification algorithms for log del Pezzo surfaces with torus action of Picard number one and given Gorenstein index. Explicit results are obtained up to Gor…
