Query: Triangulation and Classification of 2-Manifolds   This dissertation contains a comprehensive study of the topology of
2-manifolds and a complementary analysis of the work done by Edwin E. Moise, L.
V. Ahlfors and Ian Richards. Our aim is to study the well known classification
of surfaces. Here we present the technical tools needed for proving rigorously
the classification theorem and give a detailed proof using these tools.
