 Si, ya saben, me gustan las matemáticas. Topología es un tema amplio, conteniendo tanto abstracción como aplicaciones (notablemente, en la física moderna).

Lebesgue number lemma and a corollaryhttp://mathblather.blogspot.com.ar/2011/07/lebesgue-number-lemma-and-corollary.htmlIn Topology (second edition) by James R. Munkres, we have on pp175-6 a somewhat lengthy proof for the Lebesgue number lemma. Here I provide a quicker and more natural approach. Harold Calvin Marston Morsehttp://www-history.mcs.st-and.ac.uk/Biographies/Morse.html Functional analysishttp://en.wikipedia.org/wiki/Functional_analysisFunctional analysis is a branch of mathematical analysis, the core of which is formed by the study of vector spaces endowed with some kind of limit-related structure (e.g. inner product, norm, topology, etc.) and the linear operators acting upon these spaces and respecting these structures in a suitable sense.
