Gauge Theories, Supergravity and String Theory
There are four main themes:
1) Supergravity, studied both per se in its structure and solutions, and as a powerful conceptual and computational framework to explore the effective field theory description of higher dimensional theories with strings and branes.
2) The holographic correspondence, which connects supergravity with (super) conformal field theories, that are investigated in different regimes and also in various dimensions.
3) The Geometry of spacetime and target spaces, with their web of interconnecting dualities, as a basic paradigm to analyse and classify the physical string vacua, as well as making progress on several purely mathematical aspects.
