摘要翻译:
我们考虑具有左不变复结构的Nilfiologions,证明了如果Nilfiolome的Dolbeault上同调可以用左不变形式计算,那么这种结构的小变形也是左不变的。由于Console和Fino,一般情况下都是这样。我们的主要工具是复杂结构李代数的Dolbeault-上同调的模拟。

英文摘要:
We consider nilmanifolds with left-invariant complex structure and prove that small deformations of such structures are again left invariant if the Dolbeault-cohomology of the nilmanifold can be calculated using left-invariant forms. By a result of Console and Fino this is generically the case. Our main tool is an analog of Dolbeault-cohomology for Lie-algebras with complex structure.
