Branes and the swampland

S00exw00exa00exm00exp00exl00exa00exn00exd conditions are usually conjectures that divide apparently consistent (anomaly free) quantum field theories into those which can emerge from a quantum gravitational theory (the l00exa00exn00exd00exs00exc00exa00exp00exe), and those which cannot and therefore lie in the so-called s00exw00exa00exm00exp00exl00exa00exn00exd. Here the authors d00exe00exr00exi00exv00exe swampland conditions for certain supergravity theories from the consistency of sources (branes) for the fields in these theories, and assign a number of a priori consistent theories to the swampland, thus starting a program for a deeper understanding of swampland conditions.
