Toward a new construction of \tilde{D5}-singularities

Kazunori Nakamoto
University of Yamanashi

Abstract: (Joint work with Meral Tosun) For a given pair of special elements in
the Lie algebra sl(2, C)+sl(2, C), we can define a slice whose intersection
with the nilpotent subvariety is a \tilde{D5}-singularity. Here by special
element we mean an element in the Lie algebra which has semi-simple component
and nilpotent component simultaneously. We also calculated the j-function of
the exceptional curves in the minimal resolutions of \tilde{D5}-singularities
by using pairs of special elements. This is one of analogies of
Grothendieck-Brieskorn theory.
