Classification of Kaehler homogeneous manifolds of non-compact dimension two

Seyed Ruhallah Ahmadi, Bruce Gilligan

Suppose $G$ is a connected complex Lie group and $H$ is a closed complex subgroup such that $X := G / H$ is Kaehler and the codimension of the top non-vanishing homology group of $X$ …

Complexifying Lie group actions on homogeneous manifolds of non-compact dimension two

S. Ruhallah Ahmadi, Bruce Gilligan

If $X$ is a connected complex manifold with $d_{X} = 2$ that admits the holomorphic and transitive action of a (connected) Lie group $G$ , then the action extends to an action of the…

A classification of homogeneous Kähler manifolds with discrete isotropy and top nonvanishing homology in codimension two

S. Ruhallah Ahmadi

Suppose $G$ is a connected complex Lie group and $Γ$ is a discrete subgroup such that $X := G /Γ$ is Kähler and the codimension of the top non--vanishing homology group of $X$ with…

Reductivity of the Lie algebra of a bilinear form

S. Ruhallah Ahmadi, Martin Chaktoura, Fernando Szechtman

Let $f : V \times V \to F$ be a totally arbitrary bilinear form defined on a finite dimensional vector space $V$ over a a field $F$ , and let $L (f)$ be the subalgebra of $\gl(V)$ of all…
