Permutation orbifolds of sl_2 vertex operator algebras / Antun Milas, Michael Penn.
Sažetak
We analyze two types of permutation orbifolds: (i) S2-orbifolds of the universal level k vertex operator algebra Vk(sl2) and of its simple quotient Lk(sl2), and (ii) the S3-orbifold of the level one simple vertex operator algebra L1(sl2). We determine their structures and discuss related W-algebras.
