comment A simple test for degenerate eigenvalues of a holomorphic matrix-valued function?
@Daniel Is there a way to obtain it directly from the matrix?

comment An outrageous way to derive a Laurent series: why does this work?
@mistermarko I think it is clear that the order of summation cannot be changed, as $$\sum_{n=0}^\infty n^k$$ diverges for all $k\geq 0$.

revised What does it mean to say an integral exists 'in the distributional sense'?
Edited for grammar, particularly the title. This was the second google result for "in the distributional sense", so it needs some sprucing up.

comment Approximating dirac delta function with sinc functions
This feels a bit circular. Isn't the integral in question the key element of the double-Fourier-transform theorem you invoke at the end?

comment Approximating dirac delta function with sinc functions
Oh, yes, you are right - that's pretty subtle. You are again correct, it is cancellations and not absolute convergence that makes $K$ vanish, so it is essentially a version of the Riemann-Lebesgue lemma. I will redo that section when I have time.

Sorry, I didn't see that modification. You are right that the first term was incorrect. Your third term is not.

comment How can a piece of A4 paper be folded in exactly three equal parts?
And of course this has the advantage of utterly befuddling the recipient.
