Zhu's algebra, C_2-algebra and C_2-cofiniteness of parafermion vertex operator algebras (1207.3909v1)
Published 17 Jul 2012 in math.QA and math.RT
Abstract: We determine Zhu's algebra and C_2-algebra of parafermion vertex operator algebras for sl_2. Moreover, we prove the C_2-cofiniteness of parafermion vertex operator algebras for any finite dimensional simple Lie algebras.
