Arcs and monodromy
Abstract : Given a function on an algebraic variety, a lot of
information about its monodromy can be retrieved from the study of
certain spaces of arcs. We plan to discuss some of these connections
between arcs and monodromy ; in particular we intend to explain how
one can prove - and sometimes hope for - motivic analogues of some old
results on the Hodge spectrum of singularities of functions.
