## String Theory - 2º Semester 2011/2012
## Program
Bosonic Strings: Polyakov action, covariant quantization, open strings and closed strings; S-matrix,
tree-level and one-loop amplitudes; Riemann surfaces and CFT.
D-Branes and Dualities: Toroidal compactication,
closed strings and T-duality; Orbifolds; D-branes,
T-duality and Wilson lines; Gauge theory and Born-Infeld electrodynamics.
Superstrings:
Superstrings of type I and II, Ramond and Neveu-Schwarz sectors, modular invariance
and GSO projection; Superstring interactions; Calabi-Yau compactications.
More on D-Branes and Dualities:
T-duality; D-brane interactions: kinematics, dynamics and bound
states; S-duality, U-duality, M-theory and other dualities;
Black holes and AdS/CFT.
Topological String Theory: Chern-Simons theory; Kaehler and Calabi-Yau geometry; Topological
models, A and B models; Mirror symmetry; Large N dualities and matrix models; OSV conjecture.
