Let be the Witt algebra over an infinite field of prime characteristic p. In this paper, we discuss the properties of local derivations on , and prove that every local derivation on is a derivation. Moreover, it is shown that there exist some local derivations which are not derivations for the maximal subalgebra of .

素数特征中 Witt 代数的局部推导
让是素数特征p的无限域上的 Witt 代数。在本文中,我们讨论了局部导数的性质, 并证明每个局部推导是一个推导。此外,证明了存在一些局部推导,这些推导不是最大子代数的推导的.
