Non-Lorentzian M5-brane theories from holography

M-theory on AdS(7) x S-4 admits a description where the AdS(7) factor is constructed as a timelike Hopf fibration over a non-compact three dimensional complex projective space (C) over tildeP(3) [1]. We consider the worldvolume theory for M5-branes at a fixed (C) over tildeP(3) radius which, after reduction along the timelike fibre, is given by an Omega-deformed Yang-Mills theory with eight supercharges. Taking the radius to in finity then induces a classical RG flow. We construct the fixed point action which has an enhanced 24 supercharges and which can be understood as the (2, 0) theory of M5-branes on flat space reduced along a compact null Killing direction.
