In two-dimensional CFTs with a large central charge, the level-two BPZequation governs the heavy-light scalar four-point correlator when the lightprobe scalar has dimension $h= - {1\over 2}$; the corresponding linear ordinarydifferential equation can be recast into a schematic form $x^2 u_{xx}+u=0$. Inthis paper, we make an observation that in a class of four-dimensional CFTswith a large central charge, the heavy-light scalar correlator in thenear-lightcone limit obeys a similar equation, $x^3 u_{xxxy}+u=0$, when thelight scalar has dimension $\Delta=-1$. We focus on the multi-stress tensorsector of the theory and also discuss the corresponding equations for the caseswith $\Delta = -2, -3$. The solutions to these linear partial differentialequations in higher dimensions are shown, after a suitable change of variables,to reproduce the near-lightcone correlators previously obtained via holographyand the conformal bootstrap.
