Abstract:A compactification space of reductive Lie group $G$ is uniformly determined by its torus structure generated a maximal Cartan  subgroup $T$. However $T$ is not in general  a center of $G$, then there will arise an  obstruction from $T$ in the study of K/"ahler-Einstein  metrics, or K/"ahler-Ricci solitons on  $G$-group compactifications. In this talk, we will provide many interesting examples of such manifolds on which the  obstruction exists really.
