DESCRIPTION:Title: A small object argument for unique factorization systems
 \n\nAbstract: I will present a variation of Quillen small object argument\
 , inspired by Kelly\, which is better suited to construct unique factorisa
 tion systems. The construction uses the pushout product and pullback hom s
 tructure on the category of arrows. I will explain how this construction r
 ecovers the + construction involved in sheafification and I will apply it 
 to construct modalities\, localizations and left exact localizations expli
 citely from generators. All constructions are valid in 1-categories and as
  well as infinity-categories. This is a join work with C. L. Subramaniam.
