Multiplicity modulo 2 as a metric invariant

Guillaume Valette

The multiplicity of a real analytic hypersurface defined by a reduced analytic equation P = 0, is the lowest homogeneous degree in the Taylor expansion of P . Modulo 2 it is independent of the chosen reduced equation. This talk will address the following question: Is multiplicity modulo 2 a metric invariant ? I will give some partial answers.
