Kac, Pierluigi Möseneder Frajria, Paolo Papi, Ozren Perše Japanese Journal of Mathematics, September 2017, Volume 12, Issue 2, pp 261–315. https://doi.org/10.1007/s11537-017-1621-x Abstract: We present methods for computing the explicit decomposition of the minimal simple affine W-algebra as a module for its maximal affine subalgebra at a conformal level k, that is, whenever the Virasoro vectors of and coincide. A particular emphasis […]
