raise issues with large field inflationary models coming from axions.
These issues are famously absent for monodromic inflationary models, in
which the axion rolls many times its fundamental period. However, a
different version of the WGC, the 3-form WGC, predicts the existence of
membranes which can mediate fast transitions along the axion potential.
I will discuss the validity of the 3-form WGC, how typical monodromy
inflation models are not threatened by membrane-mediated transitions,
and some other details of membrane physics.
