A New Class of N=2 Topological Amplitudes
We describe a new class of N=2 topological amplitudes that compute a particular class of BPS terms in the low energy effective supergravity action. Specifically they compute the coupling F^2(\lambda\lambda)^{g-2}(d\phi)^2 where F, \lambda and \phi are gauge field strengths, gaugino and holomorphic v...
