Description
In his manuscript "Pursuing stacks", Grothendieck mentions
a certain "schematization problem", which is a far reaching extension of the
rational homotopy theory of Quillen and Sullivan. In this talk, I will
explain the schematization problem, and present several progress , applications and
open questions.
