  • Beschreibung: <p>We prove that the Eynard-Orantin symplectic invariants of the curve xy — y2 = 1 are the orbifold Euler characteristics of the moduli spaces of genus g curves. We do this by associating to the Eynard-Orantin invariants of xy — y2 = 1 a problem of enumerating covers of the two-sphere branched over three points. This viewpoint produces new recursion relations—string and dilaton equations—between the quasi-polynomials that enumerate such covers.</p>
