We study parafermion vertex algebras N − 3 / 2 ( 𝔰 𝔩 ( 2 ) ) and N − 3 / 2 ( 𝔰 𝔩 ( 3 ) ) . Using the isomorphism between N − 3 / 2 ( 𝔰 𝔩 ( 3 ) ) and the logarithmic vertex algebra 𝒲 0 ( 2 ) A 2 from [D. Adamović, A realization of certain modules for the N = 4 superconformal algebra and the affine Lie algebra A 2 ( 1 ) , Transform. Groups 21 (2) (2016) 299–327], we show that these parafermion vertex algebras are infinite direct sums of irreducible modules for the Zamolodchikov algebra 𝒲 ( 2 , 3 ) of central charge c = − 1 0 , and that N − 3 / 2 ( 𝔰 𝔩 ( 3 ) ) is a direct sum of irreducible N − 3 / 2 ( 𝔰 𝔩 ( 2 ) ) -modules. As a byproduct, we prove certain conjectures about the vertex algebra 𝒲 0 ( p ) A 2 . We also obtain a vertex-algebraic proof of the irreducibility of a family of 𝒲 ( 2 , 3 ) c modules at c = − 1 0 .

我们研究 parafermion 顶点代数ñ - 3 / 2 ( 𝔰 𝔩 ( 2 ) ) 和ñ - 3 / 2 ( 𝔰 𝔩 ( 3 ) ) . 使用之间的同构ñ - 3 / 2 ( 𝔰 𝔩 ( 3 ) ) 和对数顶点代数𝒲 0 ( 2 ) 一种 2 来自 [D. Adamović,实现某些模块的ñ = 4 超共形代数和仿射李代数一种 2 ( 1 ) ,转变。团体 21 (2) (2016) 299-327],我们证明这些对角顶点代数是 Zamolodchikov 代数的不可约模的无限直和𝒲 ( 2 , 3 ) 中央收费C = - 1 0 , 然后ñ - 3 / 2 ( 𝔰 𝔩 ( 3 ) ) 是不可约的直接和ñ - 3 / 2 ( 𝔰 𝔩 ( 2 ) ) -模块。作为副产品,我们证明了关于顶点代数的某些猜想𝒲 0 ( p ) 一种 2 . 我们还获得了一个族的不可约性的顶点代数证明𝒲 ( 2 , 3 ) C 模块在C = - 1 0 .
