Remember: Topology is a modern branch of mathematics which formalizes the processes of stretching and deforming without tearing, as well as of cutting and pasting to construct new spaces, new geometries...

I am...[edit]

a Rubik´s fan Rubik cube.png yes, i just recently learn how to solve it. See my algorithm's version at [4]. It is at a moodle´s module, to enter just check the entrar como invitado (enter as an invited) to see.

You will find (finally) an explanation of what was happening in Rudin's mind when he wrote his famous real analysis book:




algebraic, geometrical, topological ends and related stuff[edit]
