Apr 7	comment	Finding an algebra of smooth functions on a manifold with a given product. @JasonDeVito Could you explain more about your second observation? I wonder how "maximal ideal" shows up in this context. Thank you!

Mar 19	revised	What are the connections between spectral expansion and differential operator? edited tags
Mar 19	comment	What are the connections between spectral expansion and differential operator? @muzzlator Thanks for the comments! Yes, I know the spectral expansion facilitates solving differential equation, but is it the only motivation? (Just kidding: I myself find it easier to differentiate $x$ than to first write its Fourier expansion and then differentiate the expansion...)
