Extract

Stable holomorphic vector bundles over complex projective space ℙn have been studied from both the differential-geometric and the algebraic-geometric points of view.

On the differential-geometric side, the stability of E -→ ℙn can be characterized by the existence of a unique hermitian–Einstein metric on E, i.e. a metric whose curvature matrix has trace-free part orthogonal to the Fubini–Study Kähler form of ℙn (see [6], [7], and [13]). Very little is known about this metric in general and the only explicit examples are the metrics on the tangent bundle of ℙn and the nullcorrelation bundle (see [9] and [10]).
