A Remark on Equivalence between Two Formulas of the Two point Witten-Kontsevich Correlators

Abstract

We prove the equivalence between two explicit expressions for two-point Witten-Kontsevich correlators obtained by M. Bertola, B. Dubrovin, D. Yang [1] and by P. Zograf [8].

On the large genus asymptotics of psi-class intersection numbers

“…Remark 4. Formula (51) with n = 2 is given in [4], which is shown in [20] to be equivalent to Zograf's formula [31] for the 2-point intersection numbers.…”
