Matrix model superpotentials and ADE singularities
We use F. Ferrari’s methods relating matrix models to Calabi-Yau spaces in order to explain much of Intriligator and Wecht’s ADE classification of N = 1 superconformal theories which arise as RG fixed points of N = 1 SQCD theories with adjoints. We find that ADE superpotentials in the Intriligator–Wecht classification exactly match matrix model superpotentials obtained from Calabi-Yaus with cor...
متن کاملOrbifold Cohomology of ADE-singularities
We study Ruan’s cohomological crepant resolution conjecture [39] for orbifolds with transversal ADE singularities. In the An-case we compute both the orbifold cohomology ring H ∗ orb([Y ]) and the quantum corrected cohomology ring H(Z)(q1, ..., qn). The former is achieved in general, the later up to some additional, technical assumptions. We construct an explicit isomorphism between H orb([Y ])...
متن کاملDeformations of Symplectic Cohomology and Ade Singularities
Let X be the plumbing of copies of the cotangent bundle of a 2−sphere as prescribed by an ADE Dynkin diagram. We prove that the only exact Lagrangian submanifolds in X are spheres. Our approach involves studying X as an ALE hyperkähler manifold and observing that the symplectic cohomology of X will vanish if we deform the exact symplectic form to a generic non-exact one. We will construct the s...
متن کاملInstanton Induced Open String Superpotentials and Branes at Singularities
We study different aspects of the non-perturbative superpotentials induced by Euclidean E3-branes on systems of D3/D7-branes located at Abelian orbifold singularities. We discuss in detail how the induced couplings are consistent with the U(1) symmetries carried by theD3/D7 branes. We construct different compact and non-compact examples, and show phenomenologically relevant couplings like μ-ter...
متن کاملComments on Quiver Gauge Theories and Matrix Models
Dijkgraaf and Vafa have conjectured the correspondences between topological string theories, N = 1 gauge theories and matrix models. By the use of this conjecture, we calculate the quantum deformations of Calabi-Yau threefolds with ADE singularities from ADE multi-matrix models. We obtain the effective superpotentials of the dual quiver gauge theories in terms of the geometric engineering for t...
