Counting Exceptional Instantons
نویسندگان
چکیده
We show how to obtain the instanton partition function of N = 2 SYM with exceptional gauge group EFG using blow-up recursion relations derived by Nakajima and Yoshioka. We compute the two instanton contribution and match it with the recent proposal for the superconformal index of rank 2 SCFTs with E6,7 global symmetry. ckeller@theory.caltech.edu jaewon@theory.caltech.edu

Instantons and Exceptional Configurations with the Clover Action
We study exceptional modes of both the Wilson and the clover action in order to understand why quenched clover spectroscopy suffers so severely from exceptional configurations. We show that a large clover coefficient can make the exceptional modes extremely localized and thus very sensitive to short distance fluctuations. We contrast this with the case of the Wilson action where exceptional mod...
متن کاملCurve Counting and Instanton Counting
Intuitively, in four-dimensional gauge theories one counts instantons, and in twodimensional string theory one counts holomorphic curves. These correspond to the instanton counting and curve counting in the title. There is no obvious connection between them, but a remarkable physical idea called geometric engineering [9, 10, 11] dictates that they are indeed related. More precisely, the generat...
متن کاملSmall Instantons, Del Pezzo Surfaces and Type I theory
Samll instantons of exceptional groups arise geometrically by a collapsing Del Pezzo surface in a CY. We use this to explain the physics of a 4-brane probe in Type I ′ compactification

متن کاملIntersection theory of coassociative submanifolds in G2-manifolds and Seiberg-Witten invariants
We study the problem of counting instantons with coassociative boundary condition in (almost) G2-manifolds. This is analog to the open GromovWitten theory for counting holomorphic curves with Lagrangian boundary condition in Calabi-Yau manifolds. We explain its relationship with the Seiberg-Witten invariants for coassociative submanifolds. Intersection theory of Lagrangian submanifolds is an es...
