  The Formal Argument

  Andy Senger

  Reference:

   Chapter 12 of [Spectral algebraic geometry](www.math.ias.edu/~lurie/papers/SAG-rootfile.pdf)
  

  We dicuss Lurie's axiomatic deformation theory, which gives a list of criteria under which one may identify the category of formal moduli problems of a deformation context. We discuss throughout the example of formal moduli problems of animated commtuative algebras over a characteristic zero base field.
