Seiberg-Witten curves for elliptic models
I. Ennes, C. Lozano, S. Naculich +1
Four-dimensional N=2 gauge theories may be obtained from configurations of D-branes in type IIA string theory. Unitary gauge theories with two-index representations, and orthogonal…
M-Theory tested by N=2 Seiberg-Witten Theory
I. Ennes, C. Lozano, S. Naculich +2
Methods are reviewed for computing the instanton expansion of the prepotential for N=2 Seiberg-Witten theory with non-hyperelliptic curves. These results, when compared with the in…
Duality in Topological Quantum Field Theories
Carlos Lozano
This thesis presents a thorough analysis of the links between the N=4 supersymmetric gauge theory in four dimensions and its three topological twisted counterparts. Special emphasi…
Duality in the Context of Topological Quantum Field Theory
J. M. F. Labastida, Carlos Lozano
We present a summary of the progress made in the last few years on topological quantum field theory in four dimensions. In particular, we describe the role played by duality in the…
