# Linking forms revisited

@article{Conway2016LinkingFR, title={Linking forms revisited}, author={Anthony Conway and Stefan Friedl and Gerrit Herrmann}, journal={arXiv: Geometric Topology}, year={2016}, pages={493-515} }

We show that the $\mathbb{Q}/\mathbb{Z}$-valued linking forms on rational homology spheres are (anti-) symmetric and we compute the linking form of a 3-dimensional rational homology sphere in terms of a Heegaard splitting. Both results have been known to a larger or lesser degree, but it is difficult to find rigorous down-to-earth proofs in the literature.
