On toric Sarkisov Links from P^4

Abstract: According to the Sarkisov Program, a birational map between a Fano variety of Picard rank one and a Mori fibre space can be decomposed as a finite sequence of Elementary Sarkisov Links starting with the blowup of a centre. Hence, it is natural to try to understand the latter maps explicitly. In this talk we explain how to describe all possible toric Elementary Sarkisov Links starting with the blowup of a point in $\mathbb{P}^4$.
