    There's a problem in Definition 1.1.

    FMPs are not required to preserve all pull-backs between small objects, but onty pull-backs along small morphisms.

    Thanks for the alert.

    I have briefly added the missing clause now.

    But the entry remains a stub, waiting for somebody to expand on it.

  5. Adds a brief elaboration on interpreting the infinitesmally-cartesian condition in obstruction theory.

    Would it make sense to add some comments about extensions of the FMP <-> Lie-alg equivalence?
    For instance:
    - there is Benjamin Hennion's work that extend the Pridham-Lurie theorem over a cdga (rather than just a field).
    - there is Joost Nuiten's work on the equivalence between Lie algebroids and formal thickenings of a derived affine scheme (this encompasses Hennion's work mentioned above).
    - there is Lurie's work (already in DAG X) about E_n-FMPs.
    - there is my work with Campos and Nuiten that generalizes the equivalence to the case of a pair of Koszul dual operads (the theorem of Lurie and Pridham corresponds to the (Com,Lie) duality).

    Finally, there is a nice reference on FMP, that is Toën's Bourbaki seminar: https://hal.archives-ouvertes.fr/hal-01253022v2
