Pure Maths Colloquium: Function singularities with symmetries and reflection groups

Presented by Victor Goryunov, University of Liverpool (UK)

19 January 2009 16:15 in CM221

One of the cornerstones of singularity theory is Arnold-Brieskorn discovery of the correspondence between simple function singularities and Weyl ADE groups. I will show how this result extends to functions with symmetries and complex reflection groups, both linear and affine. Most attention will be paid to the monodromy and discriminants of the singularities. A crash course on vanishing topology of function singularities will be included.
