IberianStrings21 Day 4 Timo Weigand: The Swampland Program

Review by Timo Weigand on The Swampland: From Conjectures to Theorems Abstract: The `swampland’ has become known as a term to describe effective field theories which, while consistent as quantum field theories, cannot be completed into fully consistent theories of quantum gravity. A growing web of conjectures has been developed in the literature as to when a theory belongs to the swampland. In this talk I will review some of these so-called `Quantum Conjectures’, summarise the general and often times heuristic arguments in their support and highlight various connections between them. Despite the speculative character of many of the involved ideas, we will see that some of the quantum gravity conjectures can be made extremely precise and even be proven within large classes of string constructions.
