Generalized local jacobians and commutative group stacks
Bertrand Toen
In [CS01, Page 109] Grothendieck sketches the construction of a complex J_*(X) or commutative pro-algebraic groups, associated to a smooth variety X, and for which each J_i(X) is a…

Derived Foliations
Bertrand Toen, Gabriele Vezzosi
This is a book on derived foliations, that are a generalisation of classical foliations in the context of derived geometry. The text starts with the basic definitions and construct…

Foliations and stable maps
Bertrand Toën, Gabriele Vezzosi
This paper is part of an ongoing series of works on the study of foliations on algebraic varieties via derived algebraic geometry. We focus here on the specific case of globally de…
