semitoric minimal models
abstract:
a semitoric helix is a generalization of the notion of a toric fan for the case in which the acting torus is lower dimensional. the goal of this talk is to characterize the minimal models that can be obtained from a semitoric helix by a finite sequence of blowdowns. as a tool towards this end we produce a standard form for elements of $\mathrm{psl}_2(\mathbb{z})$.
