| Research Abstract |
Recently, Donaldson established the stability of a projective algebraic Kahler manifold M of constant scalar curvature essentially when the connected linear algebraic part G(M) of the group of holomorphic automorphisms of M is selnisimple.
By generalizing the concept of stability to the case where G(M) is not semisimple, we extend Donaldson's result to extremal Kahler cases even when G(M) is not semisimple. Namely, we showed that a polarized projective algebraic manifold with an extremal Kahler metric in polarization class is always stable in this generalized sense. This in particular implies that an extremal Kahler metric in a fixed integral Kahler class on a projective algebraic manifold M is unique, if any, modulo the action of G(M).
