$x-y$ swap for $(2,2p+1)$ minimal string

Abstract

We continue the study of 2D gravity -- ``matrix model'' duality on the example of $(2,2p+1)$ minimal string. We propose a reformulation of the duality, related to a more conventional one by ``$x-y$ swap'' in the language of topological recursion. This formulation elucidates some conceptual and technical difficulties in the dictionary of the duality and relation to other examples. In particular, it allows to circumvent the necessity to use ``resonance transformations'', that were previously introduced to match the worldsheet and ``matrix model'' correlators, and the expressions for minimal string amplitudes in this approach are reminiscent of the ones obtained recently for ``complex Liouville string'' theory. Using this new approach, we also formulate a conjecture on how one can compute amplitudes with operators other than tachyons in the dual theory.

v2: 35 pages, a conjecture for general formula added + other minor changes; v3: typos fixed, minor changes, matches the version accepted to Phys.Rev.D, v4: some clarifications added and more typos fixed
