Check out some problems in quantum field theory:
so far it’s the Lorentz covariance of `A ^{μ }` in the Coulomb gauge,
Furry’s theorem,
supersymmetry
and an SO(

`n`) invariant field theory.

Some notes on the Standard Model and differential geometry.

A derivation of Feynman’s path integral for QM and QFT.

Here are proofs of Cauchy’s theorem using homotopy and homology.
