DESCRIPTION:Conditional independence is an important relation in probabili
 ty\, statistics and several application areas. In this talk\, I shall iden
 tify category-theoretic structure which captures the main properties of co
 nditional independence. The structure in question arises in many contexts 
 other than probability\, including nominal sets\, computability theory and
  group theory. While the talk will mainly focus on general properties and 
 examples\, I shall end with a purely category-theoretic application: a cha
 racterisation of sheaves for the atomic (Grothendieck) topology.\n
