Research Abstract

In the field of complex geometry on homogeneous manifolds, we have been studying extensions of Kaehler structures to non-Kaehler structures, such as pseudo-Kaehler structures, locally conformally Kaehler structures, and an extension of bounded symmetric domains to non-symmetric or unbounded homogeneous domains. We have obtained some basic results including a structures theorem of homogeneous locally conformally Kaehler manifolds and a classification of four dimensional locally homogeneous locally conformally Kaehler manifolds.
