摘要
作者对秩为2的无挠的李共形代数进行了刻画.在这些代数中,作者主要关注Virasoro-型李共形代数.并且,作者描述了一种特殊Virasoro-型李共形代数的共形导子、秩为1的自由共形模和中心扩张.
In this paper, the torsion-free Lie conformal algebras of rank 2 are characterized. In these algebras, the authors pay more attention to the Virasoro-type Lie conformal algebras. Moreover, conformal derivations, free conformal modules of rank one and central extensions of a special Lie conformal algebra of Virasoro-type are determined.
