A perfect obstruction theory for a commutative ring is a morphism from a perfect complex to the cotangent complex of the ring
satisfying some further conditions. In this talk I will present work in progress on how to associate in a functorial manner commutative
differential graded algebras to such a perfect obstruction theory. The key property of the differential graded algebra is that its zeroth homology
is the ring equipped with the perfect obstruction theory. I will also indicate how the method introduced can be globalized to work on schemes
without encountering gluing issues.
