  author={Serge Lawrencenko},
This is a talk on joint work with Maŕıa José Chávez, Seiya Negami, Antonio Quintero, and Maŕıa Trinidad Villar. A triangulation of a 2-manifold M is a simplicial 2-complex with underlying space homeomorphic to M . The operation of contraction of an edge e in a triangulation T of M is the operation which consists in contracting e to a single vertex and… CONTINUE READING
