This paper collects notations, definitions and facts about distributions, differential graded algebras, continuous cohomology of topological Lie algebras, etc. and state the main results. We then recall the results of Guillemin-Losik, Losik and Haefliger, rewriting them in a for…
The first part of the book is devoted to the transport equation for a given vector field, exploiting the lagrangian structure of solutions. It also treats the regularity of solutions of some degenerate elliptic equations, which appear in the eulerian counterpart of some transpor…
