Cobordisms and Reidemeister torsions of homotopy lens spaces

چکیده
We show that any 3–dimensional homotopy lens space M that is simplehomotopy equivalent to a lens space L(p, q) is topologically s-cobordant to the lens space. It follows that M has the same multi-signature as L(p, q) and the action of π1(M) on the universal cover of M embeds in a free orthogonal action on S .

Cobordisms of Homotopy Lens Spaces
We show that any 3-dimensional homotopy lens space M that is simple-homotopy equivalent to a lens space L(p, q) is s-cobordal to this lens space. It follows that M has the same multi-signature as L(p, q) and the action of Z/pZ on the universal cover of M embeds in an orthogonal action on S. We study here 3-dimensional manifolds that have a finite cyclic fundamental group. All such manifolds are...
متن کاملof the Manifold Atlas ( 2013 ) Fake lens spaces *
A fake lens space is an orbit space of a free action of a finite cyclic group on a sphere and as such it is a generalization of a classical lens space. The invariants of fake lens spaces described here are their homotopy groups, homology groups, a certain k-invariant, the Reidemeister torsion, the ρ-invariant and certain splitting invariants. We survey the classification of fake lens spaces whi...

متن کاملThe Intersection R-Torsion for Finite Cone
Torsion invariants were originally introduced in the 3-dimensional setting by K. Reidemeister [23] in 1935 who used them to give a homeomorphism classification of 3-dimensional lens spaces. The Reidemeister torsions (R-torsions for short) are defined using linear algebra and combinational topology. The salient feature of R-torsions is that it is not a homotopy invariant but rather a simple homo...
متن کاملRefinement of Twisted Alexander Invariants and Sign-determined Reidemeister Torsions
Twisted Alexander invariants of knots are well-defined up to multiplication of units. We get rid of this multiplicative ambiguity via a combinatorial method. We can show that the refined invariants coincide with sign-determined Reidemeister torsions associated to some Euler structures. As an application, we obtain stronger necessary conditions for a knot to be fibered than those previously know...
