DESCRIPTION:Mathieu Anel\, Carnegie Mellon University\nAny 1-topos has an 
 enveloping infinity-topos defined as sheaves of spaces over the 1-topos. B
 ut surprisingly\, this construction does not send presheaf 1-topoi to pre
 sheaf infinity-topoi! I shall explain why and provide sufficient condition
 s for the envelope to stay a presheaf topoi. Applications includes the pre
 sheaves over the simplex category\, or G-equivariant presheaves.
