Non-Negativity of BMN Two-Point Functions With Three String Modes
read the original abstract
Recently, we proposed a novel entry of the pp-wave holographic dictionary, which equated the Berenstein-Maldacena-Nastase (BMN) two-point functions in free $\mathcal{N}=4$ super-Yang-Mills theory with the norm squares of the quantum unitary transition amplitudes between the corresponding tensionless strings in the infinite curvature limit, for the cases with no more than three string modes in different transverse directions. A seemingly highly non-trivial conjectural consequence, particularly in the case of three string modes, is the non-negativity of the BMN two-point functions at any higher genus for any mode numbers. In this paper, we further perform the detailed calculations of the BMN two-point functions with three string modes at genus two, and explicitly verify that they are always non-negative through mostly extensive numerical tests.

Gibbons-Hawking Entropy and BMN Strings
A proposed universal finite entropy bound for quantum gravity is introduced and linked to the Gibbons-Hawking entropy of our universe, with BMN strings suggested as an unresolved test.
