A (mostly) combinatorial proof of the homology cobordism classification of lens spaces
by
Stephan Wehrli

Coauthors: Margaret Doig

It follows implicitly from recent work in Heegaard Floer theory that lens spaces are homology cobordant exactly when they are oriented homeomorphic. We provide a new and mostly combinatorial proof using the Heegaard Floer d-invariants, which themselves may be defined combinatorially for lens spaces.
