What do the $[]$ mean? Jul 2 comment Show that $A^k$ has eigenvalues $\lambda^k$ and eigenvectors $v$. I find your proof more simple, more direct, more general and more obvious, thus much better. Jun 24 awarded Popular Question Jun 21 awarded Tenacious Jun 19 revised Why are these curves' points called rational? added 2 characters in body Jun 19 comment Why are these curves' points called rational? Thanks for the answer and explanation Jun 19 accepted Why are these curves' points called rational? Jun 19 comment Why are these curves' points called rational? Ok, thank you very much for the answer and the example. Which by the way... is it right? $i^4+i^4=2=\sqrt 2^4=4$? Should the curve have a $2$ coefficient multiplying the $x$ and $y$ terms? Jun 19 asked Why are these curves' points called rational? Jun 17 comment Proposed proof of topological result Other than that, I find it perfect. Try to separate paragraphs though, it's a bit hard to read.
