Abstract

We analyze AdS and dS swampland conjectures in a three-dimensional higher spin theory with self interacting matter, which contains conformal gravity and is almost topological. A theory of a similar type was proposed as the effective theory in the high energy phase of non-critical M-theory in 3D. With some details differing from the usual string theory story, it is found that the resulting effective theory, namely topologically massive gravity, fits well into the web of the proposed swampland conjectures. Supporting a recent proposal, in particular we find that this 3D theory gives rise to a quantum break time that scales like t(Q) similar to H-1. (C) 2021 The Authors. Published by Elsevier B.V.
