Sigma involutions associated with parafermion vertex operator algebra
Ching Hung Lam, Hiromichi Yamada
An irreducible module for the parafermion vertex operator algebra is said to be of -type if an automorphism of the fusion algebra of $K(\mathfrak{sl}_2,k)…
The structure of parafermion vertex operator algebras
Chongying Dong, Ching Hung lam, Qing Wang +1
It is proved that the parafermion vertex operator algebra associated to the irreducible highest weight module for the affine Kac-Moody algebra A_1^{(1)} of level k coincides with a…
Decomposition of the vertex operator algebra V_{\sqrt{2}D_l}
C. Dong, C. H. Lam, H. Yamada
We determine the decomposition of V_{\sqrt{2}D_l} into a sum of irreducible T-modules for general l where D_l is the root lattice of type D_l and T is the tensor product of l+1 Vir…
Decomposition of the vertex operator algebra V_{\sqrt{2}A_3}
Chongying Dong, Ching Hung Lam, Hiromichi Yamada
For vertex operator algebra V_{\sqrt{2}A_l} associated to the even lattice \sqrt{2}A_l which is \sqrt{2} times root lattice of type A_l, it was shown by Dong-Li-Maosn-Norton that t…
