 Mar28 accepted Why do Fibonacci numbers appear in stock market tick charts? Mar27 comment Why do Fibonacci numbers appear in stock market tick charts? I highly appreciate the effort you've made to post your theory. Mar27 comment Why do Fibonacci numbers appear in stock market tick charts? Thank you for the plausible and well explained theory. Mar27 awarded Benefactor Mar27 awarded Citizen Patrol Mar22 comment Why do Fibonacci numbers appear in stock market tick charts? That can also be a valid answer, but that does not render the question vacuous. There is no reason why in principle there would not be a mathematical logic behind the Fibonacci numbers.

Using text Intro. to Topo. by Mendelson Hausdorff is one of the separation axioms. You'll get to that later. Jul20 answered How does one show a topological space is metrizable? Using text Intro. to Topo. by Mendelson Jul14 comment Definition of the fundamental group It won't be even associative. The proof of associativeness and many other qualities uses homotopy between the source and outcome loops. Jul13 accepted Is $\{ a-b=y, a \oplus b=x \}$ solvable? Jul13 comment Is $\{ a-b=y, a \oplus b=x \}$ solvable? maybe in other cases, where a cannot be b so x,y cannot be 0? Jul13 asked Is $\{ a-b=y, a \oplus b=x \}$ solvable? Jul5 accepted If the * of morphisms (poly. maps) are equal, are the morphisms equal? Jul5 comment If the * of morphisms (poly. maps) are equal, are the morphisms equal? Great! is there a consequence for the fact that there is a fully faithful functor between those (or any two) categories? Jul5 comment If the * of morphisms (poly. maps) are equal, are the morphisms equal? For $t:X\rightarrow Y$, then $t_*:k[Y]\rightarrow k[x] : t_*(f(x))=f(t(x))$, so $t_*$ is a morphism between rings as is $\tau$, and * is the functor. But as I said, we never used words like functor in the lecture so I might be wrong about my definitions.
