In a spherical fusion category C, an equivariant indicator of an object in C is defined as a functional on the Grothendieck algebra of the quantum double Z(C) via generalized Frobenius-Schur indicators. The set of all equivariant indicators admits a natural action of the modular group. Using the properties of equivariant indicators, we prove a congruence subgroup theorem for modular categories. As a consequence, all modular representations of a modular category have finite images, and they satisfy a conjecture of Eholzer. In addition, we obtain two formulae for the generalized indicators, one of them a generalization of Bantay’s second indicator formula for a rational conformal field theory. This formula implies a conjecture of Pradisi-Sagnotti-Stanev, as well as a conjecture of Borisov-Halpern-Schweigert.</dcterms:abstract> <dc:language>eng</dc:language> <dc:contributor>Ng, Siu-Hung</dc:contributor> <dcterms:isPartOf rdf:resource=""/> <dcterms:bibliographicCitation>First publ. in: Communications in Mathematical Physics 300 (2010), 1, pp. 1-46</dcterms:bibliographicCitation> <dcterms:title>Congruence subgroups and generalized Frobenius-Schur Indicators</dcterms:title> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:creator>Ng, Siu-Hung</dc:creator> <dspace:isPartOfCollection rdf:resource=""/> <dc:rights>terms-of-use</dc:rights> <dc:creator>Schauenburg, Peter</dc:creator> <dcterms:issued>2010</dcterms:issued> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:date rdf:datatype="">2011-07-20T09:19:57Z</dc:date> </rdf:Description> </rdf:RDF>
