What does the sentence mean: "Convergence in this topology (uniform norm topology) is uniform convergence of the functions" ? (Gillman, Jerison : Rings of Continuous Functions) Does it mean whenever a sequence of functions on the said space…Continue

I would like to read some detailed disscussion on Uniform Norm Topology & m-topology. Can anyone suggest some standard texts/lecture notes? ("GILLMAN/JERISON: Rings of Continuous. Functions" was found to be a little bit compact for me.)Continue

Let (X, d) be a compact metric space. Suppose that f: X ---> X is a function such that d(f(x), f(y)) < d(x, y) for x ≠ y; x, y Є X. Then show that there exists x' Є X such that f(x') = x'.Continue

Speaking at the annual convention of the American Federation of Teachers recently, Bill talked about the importance of developing more effective ways to measure teaching excellence and share best practices to improve education in the classroom.

There is a philosophical doctrine known as bialetheism, with, apparently, many adherents in Australia, who take the view that there can be true contradictions. I do not wish to defend this view, but nevertheless in the next 45 minutes I will be arguing, sincerely, that mathematics both does and does not need a philosophy. Of course, the apparent contradiction can in my case be resolved in a boringly conventional way: the statement "Mathematics needs philosophy" has…

In the May 2011 issue of Scientific American mathematician John Baez co-authors "The Strangest Numbers in String Theory," an article about the octonions, an eight-dimensional number system that was discovered in the mid–19th century but that has been largely ignored until quite recently. As the name of the article implies, interest in the octonions has been rekindled…
