The uniqueness case


This paper is part of the revision of the classification of the finite simple groups. The aim is to give a solution of the so called "uniqueness case problem". Originally this problem was solved by M. Aschbacher. We do not follow his proof. The proof given in this paper uses the amalgam method, which has been used successfully in many places for dealing with weak closure.
