McKay correspondence for elliptic genera

Lev Borisov, Anatoly Libgober

We establish a correspondence between orbifold and singular elliptic genera of a global quotient. While the former is defined in terms of the fixed point set of the action, the lat…

Zariski-van Kampen theorem for higher homotopy groups

D. Chéniot, A. Libgober

This paper gives an extension of the classical Zariski-van Kampen theorem describing the fundamental groups of the complements of plane singular curves by generators and relations.…

Homotopy groups of complements and non-isolated singularities

Anatoly Libgober, Mihai Tibar

We obtain sufficient conditions for the vanishing of higher homotopy groups of the complements to hypersurfaces in in terms of the behavior at infinity and relate t…
