Nonabelian omni-Lie algebroids

In this paper,we study the structure of nonabelian omni-Lie algebroids.Firstly,taking Lie algebroid(E,[·,·]_(E,ρE))as the starting point,a nonabelian omni-Lie algebroid is defined on direct sum bundle DE⊕JE,where DE and JE are,respectively,the gauge Lie algebroid and the jet bundle of vector bundle E,and study its properties.Furthermore,it is concluded that the nonabelian omni-Lie algebroid is a trivial deformation of the omni-Lie algebroid,and the nonabelian omni-Lie algebroid is a matched pair of Leibniz algebroids.

广义n-omni-李代数胚

本文研究广义n-omni-李代数胚结构。首先,在直和丛D_(0)^(N)E⊕JE上定义D^(n-1)值配对和高阶Dorfman括号,构造广义n-omni-李代数胚,证明广义n-omni-李代数胚具有与n-omni-李代数胚类似的性质。其次,当E为平凡线丛时,构造截面Γ(ε^(n))上的高阶Dorfman括号,得到与平凡线丛_(M×R)相关的广义n-omni-李代数胚ε^(n)_(M×R)。最后,给出广义n-omni-李代数胚高阶Dirac结构,并证明图Gr(B_(△))为广义n-omni-李代数胚的高阶Dirac结构。

Omni-Representations of Leibniz Algebras

In this paper,first we introduce the notion of an omni-representation of a Leibniz algebra g on a vector space V as a Leibniz algebra homomorphism from g to the omni-Lie algebra gl(V)V.Then we introduce the omnicohomology theory associated to omni-representations and establish the relation between omni-cohomology groups and Loday-Pirashvili cohomology groups.

非交换omni-李代数胚

本文研究了非交换omni-李代数胚结构问题.首先,以李代数胚(E,[·,·]_E,ρ_E)为起点,在直和丛■上定义了非交换omni-李代数胚,其中■和■分别是向量丛E的规范李代数胚和jet丛,同时研究其性质.进一步,证明了非交换omni-李代数胚是omni-李代数胚的平凡形变,并且非交换omni-李代数胚是一个莱布尼茨代数胚的匹配对.
