Mexicana de Aviación Mexicana de Aviación Compañía Mexicana de Aviación, S.A. de C.V. (commonly known as Mexicana) was Mexico's oldest airline and one of the oldest continuously single-branded airlines (after KLM, Avianca and QANTAS), and Mexico's biggest and flagship airline before ceasing operations on August 28, 2010. The group's closure was announced by the company's recently installed management team a short time after the group filed for Concurso Mercantil (Mexican law equivalent to US Chapter 11) and US Chapter 15. On April 4, 2014, a judge declared Mexicana bankrupt and ordered to start selling off the company's assets to repay the airline's obligations.
Continuous function compact space and its codomain is Hausdorff, then it is a homeomorphism. Given a function where "X" is a topological space and "S" is a set (without a specified topology), the final topology on "S" is defined by letting the open sets of "S" be those subsets "A" of "S" for which "f"("A") is open in "X". If "S" has an existing topology, "f" is continuous with respect to this topology if and only if the existing topology is coarser than the final topology on "S". Thus the final topology can be characterized as the finest topology on "S" that
