Dynamic tropicalisation

Abstract: It is well-known that not every tropical variety can be lifted to an algebraic subvariety of the complex torus. However, any tropical variety can be lifted to a current to obtain the associated complex tropical current. Complex tropical currents have proved to be useful in complex geometry, and they can also appear as certain limits in complex dynamics. This dynamics provides a natural picture of tropicalisation (with respect to the trivial valuation), which we explain in this talk.
