YOU KNOW WHAT I JUST DID????

YOU KNOW WHAT I JUST FUCKING DID???

I DID THE FOURIER TRANSFORM ON THE LAPLACIAN TO SOLVE A POISSON PDE!!!!

I DID A FOURIER TRANSFORM. ON AN OPERATOR. I MADE AN OPERATOR INTO A FREQUENCY VARIABLE.

WHAAAT THE FUUUUCCKIN FUCK

i can not be the only person in my partial differential equations class who has no idea what's going on (also they haven't marked a SINGLE thing yet, so no idea how I'm doing going into the exam tomorrow and I think I'm just gonna have a panic attack and just... do better on future things because truly no fucking clue)

It's easy to write down explicit equations for many Calabi-Yau 3-folds (those with SU(3) holonomy), but very difficult to explicitly cast a manifold with holonomy metric G₂ or Spin(7). Robert Bryant wrote out an explicit Spin(7) and an explicit G₂ manifold in 1987: it took 49 simultaneous nonlinear PDE’s to exhibit the symmetry.
