- Homotopy groups O(N) and SO(N): $\\pi_m(O(N))$ v. s. $\\pi_m(SO(N))$
I have known the data of $\\pi_m(SO(N))$ from this Table: $$\\overset{\\displaystyle\\qquad\\qquad\\qquad\\qquad\\qquad\\qquad\\quad\\textbf{Homotopy groups of
- Dimension of SO (n) and its generators - Mathematics Stack Exchange
The generators of $SO(n)$ are pure imaginary antisymmetric $n \\times n$ matrices How can this fact be used to show that the dimension of $SO(n)$ is $\\frac{n(n-1
- Prove that the manifold $SO (n)$ is connected
The question really is that simple: Prove that the manifold $SO (n) \subset GL (n, \mathbb {R})$ is connected it is very easy to see that the elements of $SO (n
- Fundamental group of the special orthogonal group SO(n)
Also, if I'm not mistaken, Steenrod gives a more direct argument in "Topology of Fibre Bundles," but he might be using the long exact sequence of a fibration (which you mentioned)
- Diophantus Epitaph Riddle - Mathematics Stack Exchange
Diophantus' childhood ended at $14$, he grew a beard at $21$, married at $33$, and had a son at $38$ Diophantus' son died at $42$, when Diophantus himself was $80$, and so Diophantus died four years later when he was $84$ Checks out!
- orthogonal matrices - Irreducible representations of $SO (N . . .
I'm looking for a reference proof where I can understand the irreps of $SO(N)$ I'm particularly interested in the case when $N=2M$ is even, and I'm really only
- Mathematical Fallacy - The $17$ camels Problem.
So the Problem goes like this :- An old man had $17$ camels He had $3$ sons and the man had decided to give each son a property with his camels Unfortunately however, the man dies, and in his l
- The Tuesday Birthday Problem - Mathematics Stack Exchange
In case this is the correct solution: Why does the probability change when the father specifies the birthday of a son? (does it actually change? A lot of answers posts stated that the statement does matter) What I mean is: It is clear that (in case he has a son) his son is born on some day of the week
