报告摘要:
For two complex numbers a,b, the Lie algebra W(a,b) is the semidirect product of the Witt algebra and a module of the intermediate series. In this talk, all biderivations of W(a,b) are determined. Surprisingly, these Lie algebras have symmetric (and skew-symmetric) non-inner biderivations. As an applications, commutative post-Lie algebra structures on W(a,b) are obtained.
