DESCRIPTION:Title: <a href="https://researchseminars.org/talk/SemACT/18/">
 Using spectra of twisted Laplacians to detect equivalence of Riemannian co
 verings</a>\nby Gunther Cornelissen (Utrecht University) as part of Semina
 rio de álgebra\, combinatoria y teoría de Lie\n\n\nAbstract\nWe show tha
 t equivalence of two Riemannian coverings can be detected by the spectrum 
 of finitely many twisted Laplacians on the manifolds (where “twisted” 
 means constructed from a unitary representation of the fundamental group)\
 , assuming a condition on the first homology group of a common normal cove
 r. (Joint work with Norbert Peyerimhoff.)\n
