θ-Type Derivation and Derivation Superalgebra of the Finite-Dimensional Modular Lie Superalgebra W（m, n, l, t_）

摘要

In this paper F always denotes a field of characteristic p>2.We construct the finite- dimensional modular Lie superalgebra W(m,n,l,■)over a field F,define Θ-type derivation and determine the derivation superalgebra of W(m,n,l,■).
