 Jul 2 awarded Curious Mar 19 awarded Popular Question Jan 29 awarded Popular Question Mar 10 asked Question about symplectic tranformations Sep 18 comment Matrix riddle I came across Yeah, so I am not able to solve it for a 2x2 case either because I don't know what T or lambda are. The only thing I know is that Jlambda and JA are related by a similarity transform, the transformation matrix being T. But equating their eigenvalues gives me just one 5 equations... So, I'm not sure how to proceed.
