DESCRIPTION:Recent developments in high-energy physics have brought to lig
ht the need to formulate a consistent notion of distance between gravitati
onal vacua. Specifically\, within the Swampland program\, the AdS Distance
conjecture proposes to assign such a notion for AdS vacua in quantum grav
ity. Beginning with very basic AdS vacua in string theory\, I will expand
upon this concept\, providing a more formal framework for it. Firstly\, I
will introduce a precise definition of a metric for the space of conforma
l variations of AdS. This metric\, however\, turns out to be negative\, re
sulting in an ill-defined distance\, a property related to the famous conf
ormal factor problem in quantum gravity. Nonetheless\, in string theory\,
variations in the AdS conformal factor are accompanied by variations in th
e internal dimensions and background flux. Interestingly\, the inclusion o
f these variations can change the sign of the metric over the space of AdS
vacua variations. I will propose a consistent procedure for deriving the
distance between AdS vacua by introducing the notion of an "action metric\
," which accounts for all of these variations simultaneously. I will test
this procedure by focusing on AdS4 and AdS7 Freund-Rubin vacua in M-theory
and demonstrate that it yields a well-defined and positive distance.\n\nh
