LGRT 1033

The swampland program is an extremely rapidly growing topic in formal particle theory. The goal of the program is to identify universal features of quantum gravities, with the potential to generate experimentally testable predictions. The primary approach pursued so far has been to formulate conjectures based on the available constructions in string theory, as well as on heuristic arguments about the consistency requirements of quantum gravity, and to explore their consequences.

This workshop aims to address the growing need to rigorously test swampland conjectures, to prove them if possible (either based on a particular UV assumption, such as perturbative string theory, or more generally from first principles), and also to rule out incorrect conjectures.
