摘要翻译：
李代数g上平坦的无扭连接或左对称代数结构的存在，在g+g上得到了正则定义的复结构，在g+g^*上得到了辛结构。我们证明了控制复形和辛形变形理论的关联微分Gerstenhaber代数是同构的。这提供了Merkulov所建议的一类“弱镜像对称”的例子。对于维数为4和6的幂零代数，给出了半直积G+G和G+G^*的同构类。给出了一个不等价伪k“Ahler结构的单参数族。

英文摘要：
  The existence of a flat torsion-free connection, or left symmetric algebra structure on a Lie algebra g gives rise to a canonically defined complex structure on g+g and a symplectic structure on g+g^*. We verify that the associated differential Gerstenhaber algebras controlling the deformation theories of the complex and symplectic form are isomorphic. This provides a class of examples of "weak mirror symmetry" as suggested by Merkulov. For nilpotent algebras in dimension 4 and 6 the isomorphism classes of the semi-direct products g+g and g+g^* are listed. A one-parameter family of inequivalent pseudo-K\"ahler structures is given.
