Milagros Izquierdo (Linköping):
Equisymmetric strata of the singular locus of the moduli space of
Riemann surfaces of genus 4

**Abstract.**
The moduli space M_g is the space of analytic
equivalence classes
of Riemann surfaces of a fixed genus g. The space M_g has a
natural equisymmetric
stratification, each stratum consists of the Riemann surfaces with an
automorphisms group acting in
a given topological way. Using Fuchsian groups we describe the
equisimmetrical stratification for the
moduli space of surfaces of genus 4. This is a joint work with Antonio F.
Costa.
