Equivariant Casson invariants and links of singularities

Olivier Collin, Nikolai Saveliev

Research output: Contribution to journalArticle


The equivariant Casson invariants and links of singularities were discussed. The graph homology spheres endowed with an involution representing them as double branched cover of S3 with branch set a Montesinos knot were elaborated. An explicit formula for the equivariant Casson invariant of such manifold was also derived.
