Circle of Sarkisov links on a Fano $3$-fold

Algebraic Geometry 2022-07-22 v2

Abstract

For a general Fano 33-fold of index 11 in the weighted projective space P(1,1,1,1,2,2,3)\mathbb{P}(1,1,1,1,2,2,3) we construct 22 new birational models that are Mori fibre spaces, in the framework of the so-called Sarkisov program. We highlight a relation between the corresponding birational maps, as a circle of Sarkisov links, visualising the notion of relations (due to Kaloghiros) in Sarkisov program.
