Two Two - Dimensional Supergravity Theories from Calabi - Yau Four - Folds
We consider two-dimensional supergravity theories with four supercharges constructed from compactification of Type II string theory on a generic Calabi-Yau four-fold. In Type IIA and Type IIB cases, respectively, new superspace formulations of N = (2, 2) and N = (0, 4) dilaton supergravities are found and their coupling to matter multiplets is discussed. 1. Introduction For a long time, compact...
متن کاملCFT’s From Calabi-Yau Four-folds
We consider F/M/Type IIA theory compactified to four, three, or two dimensions on a Calabi-Yau four-fold, and study the behavior near an isolated singularity in the presence of appropriate fluxes and branes. We analyze the vacuum and soliton structure of these models, and show that near an isolated singularity, one often generates massless chiral superfields and a superpotential, and in many in...
متن کاملLectures on D-branes, Gauge Theories and Calabi-Yau Singularities
These lectures, given at the Chinese Academy of Sciences for the BeiJing/HangZhou International Summer School in Mathematical Physics, are intended to introduce, to the beginning student in string theory and mathematical physics, aspects of the rich and beautiful subject of D-brane gauge theories constructed from local Calabi-Yau spaces. Topics such as orbifolds, toric singularities, del Pezzo ...
متن کامل2 00 7 Enumerative geometry of Calabi - Yau 4 - folds
Gromov-Witten theory is used to define an enumerative geometry of curves in Calabi-Yau 4-folds. The main technique is to find exact solutions to moving multiple cover integrals. The resulting invariants are analogous to the BPS counts of Gopakumar and Vafa for Calabi-Yau 3-folds. We conjecture the 4-fold invariants to be integers and expect a sheaf theoretic explanation. Several local Calabi-Ya...
متن کاملEnumerative Geometry of Calabi-Yau 5-Folds
The original recursions for A2(d) ≡ nd(ψ̃, H) and B1(d1, d2) ≡ nd1d2(|;H2) do not involve any of the other terms. Using Lemma 1, the formulas (A.2) and (A.3) can be shown to satisfy the two recursions. The original formula for A1(d) ≡ nd(ψ̃H) expresses A1(d) in terms of B1(d1, d2). The formula (A.1) follows from (A.3) and Lemma 2. Originally, there are also the terms nd(ψ̃H,H ), but it is not hard...
