DESCRIPTION:When planets form in protoplanetary discs\, they interact grav
 itationally with the gas in the disc. This interaction excites spiral dens
 ity waves which\, when they dissipate\, can cause the formation of gaps an
 d rings. These gaps can be seen in observations from ALMA and JSWT\, and c
 ould be used to infer the existence and location of planets. However\, int
 erpreting these observations requires robust models of how the planet and 
 disc interact and how gaps form. I will show new work that provides a line
 ar relationship between the angular momentum deposition caused by a planet
  and the resultant surface density evolution. I will discuss how this anal
 ytic model can help us understand the evolution of gap structures in visco
 us and inviscid discs.
