 Jul 2 awarded Curious Nov 27 awarded Yearling Oct 12 comment Question on dense sets possible duplicate of Link between a Dense subset and a Continuous mapping Oct 12 awarded Citizen Patrol Nov 27 awarded Yearling Jun 8 awarded Caucus Apr 10 accepted Semidirect Products with GAP Apr 5 comment Semidirect Products with GAP Thanks @JacobSchlather, I'll read those pages and post a solution if I can figure it out. Others are of course still welcome to help :) Apr 5 asked Semidirect Products with GAP Mar 22 comment What is the “standard basis” for fields of complex numbers? @QiaochuYuan, yes, sorry, that wasn't a particularly relevant response! Mar 5 awarded Enthusiast Feb 20 comment Understanding the equivariant rank theorem Wait, maybe this is a silly question. In the general case we know $T_pM$ and $T_{\varphi(p)}N$ have the same dimension, so we can just map the basis vectors for one bijectively to the basis vectors of the other?

Feb 19 comment How to show that derivative of $\phi(v)$ with respect to $v$ is $\phi'( v)= a(1-\phi^2(v))/2$ Write out the $\tanh$ function using exponentials and then try to get the above relations. Check the wikipedia article on hyperbolic trigonometric functions.

Perhaps not technical, but I much prefer $GL(n,\mathbb{R})\leq GL(n,\mathbb{C})$ simply because $\mathbb{C}$ is an extension of $\mathbb{R}$
