Many aspects of the theory of “topological strings” (the A-model and the B-model) proceed in close analogy (just simpler) to the “physical” string theory. Accordingly, as the latter can usefully be organized as the dimensional reduction of a conjectured UV-completion of 11-dimensional supergravity – M-theory – there seems to be an analogous higher dimensional organizational principle for topological strings, hence termed topological M-theory.
One way to understand it is as a TQFT-analog of the M2-brane sigma-model, the topological membrane.
The notion has been introduced in
