摘要

We define and compute algebraically a “perturbative part” of protected sphere correlation functions in the M2 brane SCFTs. These correlation functions are expected to have a holographic description in terms of twisted, Ω-deformed M-theory. We uncover a hidden perturbative triality symmetry which supports this conjecture. We also discuss some variants of the setup, involving M2 branes at Ak singularities and D3 branes with a transverse compact direction.
