If (M4, g0) is a finite volume quotient of the complex hyperbolic space, we prove that any Einstein, complete, bounded curvature metric g on M , such that the diameter of horocycles goes to zero and the mean curvature of the horocycles is bounded from below by a positive constant, is equal (up to a diffeomorphism) to the standard complex hyperbolic metric g0. This generalizes a theorem of LeBrun in the compact case. To prove the theorem, we produce a solution of the Seiberg-Witten equations on the noncompact manifold (M, g) ; in fact, M can be compactified as an orbifold M , and we get the wanted solution as a limit of solutions for a sequence of metrics on M , which approximate g.
