Description

In this talk I will show how some special actions of $\mathbb C^*$ on smooth projective varieties are related to birational transformations between the sink and the source of the action, discussing examples and related problems.

This is a joint work with Jaroslaw Wisniewski, Luis E. Solá Conde and Eleonora A. Romano.
