SUMMARY:Pablo PORTILLA (Laboratoire Paul Painlevé at Université de Lille)
 : Characterizing the geometric monodromy group of an isolated plane curve 
 singularity
DESCRIPTION:Pablo PORTILLA: In this talk we will explain an intrinsic chara
 cterisation of the geometric monodromy group of an isolated plane curve si
 ngularity as the stabiliser in the mapping class group of the Milnor fiber
  of the relative isotopy class of a canonical vector field. We will also d
 iscuss two interesting consequences of this result: an easy and efficient 
 criterion for detecting whether a simple closed curve in the Milnor fiber 
 is a geometric vanishing cycle or not\, and the non-injectivity of the nat
 ural representation of the versal unfolding of the singularity. This is a 
 joint work with Nick Salter.
