摘要
We give small deformations of a left-invariant complex structure on each simply connected semisimple compact Lie group of even dimension which are not biholomorphic to any left-invariant (right-invariant) complex structure by using the Kuranishi space. On such deformed complex manifolds, we prove the Borel-Weil-Bott type theorem, and we compute the cohomology of holomorphic tangent bundles.
