N = 2 dualities

- D. Gaiotto
- Physics
- 17 April 2009

A bstractWe study the generalization of S-duality and Argyres-Seiberg duality for a large class of N = 2 superconformal gauge theories. We identify a family of strongly interacting SCFTs and use them… Expand

Liouville Correlation Functions from Four-Dimensional Gauge Theories

- L. Alday, D. Gaiotto, Yuji Tachikawa
- Physics, Mathematics
- 17 June 2009

We conjecture an expression for the Liouville theory conformal blocks and correlation functions on a Riemann surface of genus g and n punctures as the Nekrasov partition function of a certain class… Expand

S-duality of boundary conditions in N=4 super Yang-Mills theory

- D. Gaiotto, E. Witten
- Physics
- 23 July 2008

By analyzing brane configurations in detail, and extracting general lessons, we develop methods for analyzing S-duality of supersymmetric boundary conditions in N=4 super Yang-Mills theory. In the… Expand

Generalized global symmetries

- D. Gaiotto, A. Kapustin, N. Seiberg, Brian Willett
- Physics
- 16 December 2014

A bstractA q-form global symmetry is a global symmetry for which the charged operators are of space-time dimension q; e.g. Wilson lines, surface defects, etc., and the charged excitations have q… Expand

Wall-crossing, Hitchin Systems, and the WKB Approximation

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 23 July 2009

We consider BPS states in a large class of d = 4,N = 2 eld theories, obtained by reducing six-dimensional (2; 0) superconformal eld theories on Riemann surfaces, with defect operators inserted at… Expand

Four-Dimensional Wall-Crossing via Three-Dimensional Field Theory

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 29 July 2008

We give a physical explanation of the Kontsevich-Soibelman wall-crossing formula for the BPS spectrum in Seiberg-Witten theories. In the process we give an exact description of the BPS instanton… Expand

Framed BPS states

- D. Gaiotto, G. Moore, A. Neitzke
- Physics, Mathematics
- 1 June 2010

We consider a class of line operators in d = 4,N = 2 supersymmetric field theories which leave four supersymmetries unbroken. Such line operators support a new class of BPS states which we call… Expand

Loop and surface operators in $ \mathcal{N} = 2 $ gauge theory and Liouville modular geometry

- L. Alday, D. Gaiotto, S. Gukov, Yuji Tachikawa, H. Verlinde
- Physics
- 6 September 2009

Recently, a duality between Liouville theory and four dimensional $ \mathcal{N} = 2 $ gauge theory has been uncovered by some of the authors. We consider the role of extended objects in gauge theory,… Expand

The gravity duals of N=2 superconformal field theories

- D. Gaiotto, J. Maldacena
- Physics
- 28 April 2009

We study the gauge/gravity duality for theories with four dimensional ${\cal N}=2$ supersymmetries. We consider the large class of generalized quiver field theories constructed recently by one of us… Expand

Notes on superconformal Chern-Simons-Matter theories

- D. Gaiotto, X. Yin
- Physics
- 27 April 2007

The three dimensional = 2 supersymmetric Chern-Simons theory coupled to matter fields, possibly deformed by a superpotential, give rise to a large class of exactly conformal theories with Lagrangian… Expand
