Let f : (M,p)\to (M',p') be a formal biholomorphic mapping between two germs
of real analytic hypersurfaces in \C^n, p'=f(p). Assuming the source manifold
to be minimal at p, we prove the convergence of the so-called reflection
function associated to f. As a consequence, we derive the convergence of formal
biholomorphisms between real analytic minimal holomorphically nondegenerate
hypersurfaces. Related results on partial convergence of formal biholomorphisms
are also obtained.Comment: 15 pages, Late
