论文摘要
给定一个复杂的简单谎言代数$ \ mathfrak {g} $和一个正整数$ \ ell $,在假设$λ\ggμ$下,我们表明,$ v(λ+wμ)$,$ w fuse $ w \ $ $ w \ $ $ w \ y Mathfrak {g g} $的不可约表示的表示,并在$ w \中出现。 $ v(μ)$。在此特殊情况下,这验证了融合产品的PRV组件的存在。
Given a complex simple Lie algebra $\mathfrak{g}$ and a positive integer $\ell$, under the assumption $λ\ggμ$, we show that irreducible representations of $\mathfrak{g}$ of the form $V(λ+wμ)$, $w\in W,$ with level at most $\ell$ appear in the fusion product of $V(λ)$ and $V(μ)$. This verifies the existence of PRV components for the fusion product in this special case.
