Surface operators, dual quivers and contours
S. K. Ashok, S. Ballav, M. Billo' +5
We study half-BPS surface operators in four dimensional N=2 SU(N) gauge theories, and analyze their low-energy effective action on the four dimensional Coulomb branch using equivar…

Surface operators in 5d gauge theories and duality relations
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study half-BPS surface operators in 5d N=1 gauge theories compactified on a circle. Using localization methods and the twisted chiral ring relations of coupled 3d/5d quiver gaug…

Surface operators, chiral rings, and localization in N=2 gauge theories
S. K. Ashok, M. Billo, E. Dell'Aquila +4
We study half-BPS surface operators in supersymmetric gauge theories in four and five dimensions following two different approaches. In the first approach we analyze the chiral rin…
