    Modular structure theory on Hom-Lie algebras

    Full text link
    The aim of this paper is to transfer the restrictedness theory to Hom-Lie algebras. The concept of restricted Hom-Lie algebras which is introduced in \cite{BM2} will be used in this paper. First, the existence of pp-structures on a Hom-Lie algebra is studied and the direct sum of restricted Hom-Lie algebras is analyzed. Then, the definition of a restrictable Hom-Lie algebra is given and the equivalence relation between restrictable Hom-Lie algebras and restricted Hom-Lie algebras is constructed. Finally, the pp-envelopes of a Hom-Lie algebra are defined and studied.Comment: 18page

    We construct 3-Hom-Lie superalgebras on a commutative Hom-superalgebra by means of involution and even degree derivation. We construct a representation of induced 3-Hom-Lie superalgebras by means of supertrace

    No full text
    Abstract The paper studies the structure of restricted hom-Lie algebras. More specifically speaking, we first give the equivalent definition of restricted hom-Lie algebras. Second, we obtain some properties of p-mappings and restrictable hom-Lie algebras. Finally, the cohomology of restricted hom-Lie algebras is researched

    summary:The paper studies nilpotent nn-Lie superalgebras over a field of characteristic zero. More specifically speaking, we prove Engel's theorem for nn-Lie superalgebras which is a generalization of those for nn-Lie algebras and Lie superalgebras. In addition, as an application of Engel's theorem, we give some properties of nilpotent nn-Lie superalgebras and obtain several sufficient conditions for an nn-Lie superalgebra to be nilpotent by using the notions of the maximal subalgebra, the weak ideal and the Jacobson radical
