On Link Invariants and Topological String Amplitudes
We explicitly show that the new polynomial invariants for knots, upto nine crossings, agree with the Ooguri-Vafa conjecture relating Chern-Simons gauge theory to topological string theory on the resolution of the conifold. From the multi-component link invariants in SU(N) Chern-Simons theory, we suggest a form for the new polynomial invariants. Email: [email protected] Email: [email protected]...
متن کاملGlobal Properties of Topological String Amplitudes and Orbifold Invariants
We derive topological string amplitudes on local Calabi-Yau manifolds in terms of polynomials in finitely many generators of special functions. These objects are defined globally in the moduli space and lead to a description of mirror symmetry at any point in the moduli space. Holomorphic ambiguities of the anomaly equations are fixed by global information obtained from boundary conditions at f...
متن کاملTopological 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 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 کاملHeterotic, Open and Unoriented String Theories from Topological Membrane
In this work I consider several topics in the Topological Membrane (TM) approach to string theory. In TM the string worldsheets emerge as boundary theories of the 3D membrane with topology Σ × [0, 1]. The string dynamics is generated in this way from the bulk physics, namely from the 3D Topologically Massive Gauge Theory (TMGT) and Topologically Massive Gravity (TMG). Both (equivalent) path int...
