@bolbteppa, When you say diagonalize do you mean take a change of variables? Or do you mean just re-express this exponential? I'm afraid my calculus background is a bit weak, not very familiar with integrating forms
If $T$ is an invertible matrix, and for matrices $B$ and $C$, and we have that $\|TA-TB\|<\epsilon$, can we say that $A$ and $B$ are close to each other in some sense?
but it's a little far out there, and Jung was basically a cult leader. but there was something fascinating about it. though i imagine in practice it's usually quite banal
i don't know if it's up your alley, @Nick, but for some reason this problem is really stumping me and i would really appreciate it if someone could give me a clue what i'm missing
