The vanishing cycles of curves in toric surfaces II

Rémi Crétois, Lionel Lang

We resume the study initiated in \cite{CL}. For a generic curve $C$ in an ample linear system $∣ L ∣$ on a toric surface $X$ , a vanishing cycle of $C$ is an isoto…

Amoebas of curves and the Lyashko-Looijenga map

Lionel Lang

For any curve $V$ in a toric surface $X$ , we study the critical locus $S (V)$ of the moment map $μ$ from $V$ to its compactified amoeba $μ(\mathcal{V})…

The vanishing cycles of curves in toric surfaces I

Rémi Crétois, Lionel Lang

This article is the first in a series of two in which we study the vanishing cycles of curves in toric surfaces. We give a list of possible obstructions to contract vanishing cycle…
