- diffhist Extensions of symmetric operators 13:41 +83 ~2025-38692-22 talk contribs (Fix mathematical error in the example: the original transformation was not unitary because ||e^{x}|| not equal ||e^{-x}||; corrected the unitary transformation between deficiency subspaces, updated the domain formula and resulting boundary condition.)
- diffhist m Fourier transform 01:55 −11 Michaelala25 talk contribs (I suspect there might've been an issue with the definition of the group law before - I checked by hand and it seemed it wasn't even associative. I believe this updated definition is the correct one and more closely matches the one in R. Howe's 1980 paper.)
