| Let F be a field of characteristic p > 2 . In this paper, the modular Liesuperalgebras K(m, n,l,(?)) is constructed. Its some important properties are given.By investigating dimensions of images of some elements of K(m, n,l,(?)) , weprove that the noncontractible filtration of K(m, n,l,(?)) is invariant. Furthermore,the sufficient and necessary condition that K(m, n,l,(?)) and K(m′,n′,l′,(?)′) areisomorphic is given. |
