A spectral approach to the linking number in the 3-torus

Vol. 307 (2020), No. 2, 257–281
##### Abstract

Given a closed Riemannian manifold and a pair of multicurves in it, we give a formula relating the linking number of the latter to the spectral theory of the Laplace operator acting on differential 1-forms. As an application, we compute the linking number of any two multigeodesics of the flat torus of dimension 3, generalising a result of P. Dehornoy.
