We compute the h olographic thermal two-point function of scalar operators in the boundary theory. We present analytic expressions for leading corrections due to loc al quartic interactions in the bulk\, with an arbitrary number of derivati ves and for any number of spacetime dimensions. The solutions are fixed by judiciously picking an ansatz and imposing consistency conditions. The co nditions include analyticity properties\, consistency with the operator pr oduct expansion\, and the Kubo-Martin-Schwinger condition. For the case wi thout any derivatives we show agreement with an explicit diagrammatic comp utation. The structure of the answer is suggestive of a thermal Mellin amp litude. Additionally\, we derive a simple dispersion relation for thermal two-point functions which reconstructs the function from its discontinuity .\n\nPassword: 496169\n LOCATION:https://researchseminars.org/talk/UKYhepth/43/ END:VEVENT END:VCALENDAR
