    • El gas primordial y el origen de las anisotropías de temperatura de la radiación del fondo cósmico 

      Peña Cervantes, Luis Fernando (Universidad Michoacana de San Nicolás de Hidalgo, 2011-09)
      We can think of the whole universe as a big oven. At first it was at an extraordinarily high temperature which in the course of its evolution has diminished radically, as we can now observe it in the cosmic background ...

    • El método probabilístico en matemáticas discretas 

      Téllez Gómez, Héctor Manuel (Universidad Michoacana de San Nicolás de Hidalgo, 2011-09)
      The next paper deals with the probabilistic method. The probabilistic method is a non-constructive tool that uses probability theory to demonstrate the existence of mathematical "objects." Since there is no standard way ...
