An $S L_{2} (R)$ -Casson invariant and Reidemeister torsions

arXiv:2005.06132

Abstract

We define an $S L_{2} (R)$ -Casson invariant of closed 3-manifolds. We also observe procedures of computing the invariants in terms of Reidemeister torsions. We discuss some approach of giving the Casson invariant some gradings.

arXiv commentThis manuscript has been withdrawn by the author because the arguments, as presented, are not sufficiently precise
