DESCRIPTION:Sean Monahan\nToric varieties are beloved in algebraic geometr
 y because of their combinatorial theory using polyhedral fans\; horospheri
 cal varieties vastly generalize this theory using so-called coloured fans.
  In the first 30 minutes\, I will briefly introduce these horospherical va
 rieties and their combinatorial theory (knowledge of toric varieties is no
 t necessary). Then\, in the next 45 minutes\, I will introduce horospheric
 al stacks -- extending horospherical varieties into the larger world of al
 gebraic stacks\, and generalizing the known class of toric stacks -- and d
 iscuss my results on developing their combinatorial theory.
