Belorousski-Pandharipande relation in dGBV algebras
  We prove that the genus expansion of solutions of the WDVV equation constructed from dGBV algebras satisfy the differential equation determined by the Belorousski-Pandharipande relation in cohomology of the moduli space of curves $\bar{\mathcal{M}}_{2,3}$.
