--- res: bibo_abstract: - 'Given a possibly reducible and non-reduced spectral cover π: X → C over a smooth projective complex curve C we determine the group of connected components of the Prym variety Prym(X/C). As an immediate application we show that the finite group of n-torsion points of the Jacobian of C acts trivially on the cohomology of the twisted SL n-Higgs moduli space up to the degree which is predicted by topological mirror symmetry. In particular this yields a new proof of a result of Harder-Narasimhan, showing that this finite group acts trivially on the cohomology of the twisted SL n stable bundle moduli space.@eng' bibo_authorlist: - foaf_Person: foaf_givenName: Tamas foaf_name: Tamas Hausel foaf_surname: Hausel foaf_workInfoHomepage: http://www.librecat.org/personId=4A0666D8-F248-11E8-B48F-1D18A9856A87 - foaf_Person: foaf_givenName: Christian foaf_name: Pauly, Christian foaf_surname: Pauly bibo_doi: 10.2140/gt.2012.16.1609 bibo_issue: '3' bibo_volume: 16 dct_date: 2012^xs_gYear dct_publisher: University of Warwick@ dct_title: Prym varieties of spectral covers@ ...
