SUMMARY:Adjunctions induced by Kan Extensions between Grothendieck Toposes

DESCRIPTION:It is well know that a flat functor between two small categori
 es will induce an adjoint triple between the respective presheaf categorie
 s via left and right Kan extensions. I will explain how certain conditions
  imposed on the flat functor can enable us to restrict this adjunction to 
 subcategories of sheaves\, and I will comment on the significance of this 
 in the study of local geometric morphisms.\n\nI will briefly sketch a gent
 le introduction to Kan extensions for those who aren't yet familiar with t
 hem.
