Some algebra related to $P$ -and $Q$ -polynomial association schemes

Tatsuro Ito, Kenichiro Tanabe, Paul Terwilliger

Let $K$ denote a field, and let $V$ denote a vector space over $K$ with finite positive dimension. Consider a pair of linear transformations $A : V \to V$ and $A^{*} : V \to V$ that satisf…

Z_3 symmetry and W_3 algebra in lattice vertex operator algebras

C. Dong, C. H. Lam, K. Tanabe +2

The W_3 algebra of central charge 6/5 is realized as a subalgebra of the vertex operator algebra V_{\sqrt{2}A_2} associated with a lattice of type \sqrt{2}A_2 by using both coset c…

Uniform product of A_{g,n}(V) for an orbifold model V and G-twisted Zhu algebra

Masahiko Miyamoto, Kenichiro Tanabe

Let V be a vertex operator algebra and G a finite automorphism group of V. For each g\in G and nonnegative rational number n\in {\mathbb Z}/|g|, a g-twisted Zhu algebra A_{g,n}(V)…
