设$p(t)\in\mathbb C[t]$是一个具有不同根和非零常数项的多项式。本文利用Fa\'adeBruno公式和Bell多项式描述了超椭圆流李代数$\mathfrakg\otimes R$的泛中心扩张,其坐标环的形式为$R=\mathbb C[t,t^{-1},u\,|,u^2=p(t)]$。
Let $p(t)\in\mathbb C[t]$ be a polynomial with distinct roots and nonzero constant term. We describe, using Fa\'a de Bruno's formula and Bell polynomials, the universal central extension in terms of generators and relations for the hyperelliptic current Lie algebras $\mathfrak g\otimes R$ whose coordinate ring is of the form $R=\mathbb C[t,t^{-1},u\,|\, u^2=p(t)]$.
