原始语种摘要: Abstract(#br)In this paper, we explore natural connections among trigonometric Lie algebras, (general) affine Lie algebras, and vertex algebras. Among the main results, we obtain a realization of trigonometric Lie algebras as what were called the covariant algebras of the affine Lie algebra A ˆ of Lie algebra A = gl ∞ ⊕ gl ∞ with respect to certain automorphism groups. We then prove that restricted modules of level ℓ for trigonometric Lie algebras naturally correspond to equivariant quasi modules for the affine vertex algebras V A ˆ ( ℓ , 0 ) (or V A ˆ ( 2 ℓ , 0 ) ). Furthermore, we determine irreducible modules and equivariant quasi modules for the simple vertex algebra L A ˆ ( ℓ , 0 ) with ℓ a positive integer. In particular, we prove...
