Feynman diagrams and $\mathrm{\Omega }$-deformed M-theory

We derive the simplest commutation relations of operator algebras associated to M2 branes and an M5 brane in the $\mathrm{\Omega }$-deformed M-theory, which is a natural set-up for Twisted holography. Feynman diagram 1-loop computations in the twisted-holographic dual side reproduce the same algebraic relations.
