N2 - We study the Masur–Veech volumes (Formula presented.) of the principal stratum of the moduli space of quadratic differentials of unit area on curves of genus (Formula presented.) with (Formula presented.) punctures. We show that the volumes (Formula presented.) are the constant terms of a family of polynomials in (Formula presented.) variables governed by the topological recursion/Virasoro constraints. This is equivalent to a formula giving these polynomials as a sum over stable graphs, and retrieves a result of [Delecroix, Goujard, Zograf, Zorich, Duke J. Math 170 (2021), no. 12, math.GT/1908.08611] proved by combinatorial arguments. Our method is different: it relies on the geometric recursion and its application to statistics of hyperbolic lengths of multicurves developed in [Andersen, Borot, Orantin, Geometric recursion, math.GT/1711.04729, 2017]. We also obtain an expression of the area Siegel–Veech constants in terms of hyperbolic geometry. The topological recursion allows numerical computations of Masur–Veech volumes, and thus of area Siegel–Veech constants, for low (Formula presented.) and (Formula presented.), which leads us to propose conjectural formulae for low (Formula presented.) but all (Formula presented.). We also relate our polynomials to the asymptotic counting of square-tiled surfaces with large boundaries.
