Mohamed Boucetta, Mohammed Wadia Mansouri

摘要:

本文给出了四维单连通李群上第1型左不变广义复结构的完全分类,并计算了每类复结构的不变广义Dolbeault上同调、不变广义Bott-Chern上同调和不变广义Aeppli上同调.我们还对四维单连通李群上的左不变广义Kähler结构进行了分类.

英文摘要:

We give a complete classification of left invariant generalized complex structures of type 1 on four dimensional simply connected Lie groups and we compute for each class its invariant generalized Dolbeault cohomology, its invariant generalized Bott-Chern cohomology and its invariant generalized Aeppli cohomology. We classify also left invariant generalized Kähler structures on four dimensional simply connected Lie groups.
