"A biography of the Weak Gravity Conjecture"

Lukas Witkowski

In its original form the Weak Gravity Conjecture (WGC) is a proposed
constraint on gauge theories coupled to gravity. From this simple
starting point one can however arrive at far reaching implications: if
true, the WGC gives rise to severe constraints on models of large-field
inflation and it may have important consequences for the stability of
the string theory landscape. It is this connection to inflation, which
has led to renewed interest in the WGC in the recent years. However, the
progress made in this time comes with a price: there exist several
competing formulations of the conjecture. Further, there are various
generalisations with varying levels of support. While more evidence has
been gathered, there is still no proof. In this talk I want to give a
status report on the WGC: in particular, I will present the current
formulations, recent evidence and the status quo on applications to
cosmology and particle physics.
