Topological Amplitudes in String Theory
We show that certain type II string amplitudes at genus g are given by the topologi-cal partition function F g discussed recently by Bershadsky, Cecotti, Ooguri and Vafa. These amplitudes give rise to a term in the four-dimensional effective action of the form g F g W 2g , where W is the chiral superfield of N = 2 supergravitational multi-plet. The holomorphic anomaly of F g is related to non-l...
متن کاملInstanton amplitudes in open-closed topological string theory
I use the universal instanton formalism to discuss quantum effects in the openclosed topological string theory of a Calabi-Yau A-model, in the presence of a multiplywrapped ‘Floer’ D-brane. This gives a precise meaning (up to the issue of compactifying the relevant moduli spaces) to the instanton corrections which affect sigma model and topological string amplitudes. The cohomological formalism...
متن کاملTopological Amplitudes and Physical Couplings in String
In these lectures, we review the main properties of the topological theory obtained by twisting the N = 2 two-dimensional superconformal algebra, associated to supersymmetric string compactifications. In particular, we describe a set of physical quantities in string theory that are computed by topological amplitudes. These are in general higher-dimensional F -terms in the low energy effective s...
متن کاملOpen string amplitudes and large order behavior in topological string theory
We propose a formalism inspired by matrix models to compute open and closed topological string amplitudes in the B-model on toric Calabi–Yau manifolds. We find closed expressions for various open string amplitudes beyond the disk, and in particular we write down the annulus amplitude in terms of theta functions on a Riemann surface. We test these ideas on local curves and local surfaces, provid...
متن کاملString Amplitudes from Moyal String Field Theory
We illustrate a basic framework for analytic computations of Feynman graphs using the Moyal star formulation of string field theory. We present efficient methods of computation based on (a) the monoid algebra in noncommutative space and (b) the conventional Feynman rules in Fourier space. The methods apply equally well to perturbative string states or nonperturbative string states involving D-b...
