经典N=2李共形超代数的导子和第二上同调群
Derivations and the Second Cohomology Group of the Classical N=2 Lie Conformal Superalgebra
研究了经典N=2李共形超代数的导子和第二上同调群的结构，并应用第二上同调群的结果确定了该李共形超代数的泛中心扩张.
We studied the derivations and the second cohomology group of the classical N=2 Lie conformal superalgebra. Furthermore, we investigated the universal central extension of this Lie conformal superalgebra by applying the result on the second cohomology group.
