Differential forms in Heisenberg groups and div-curl systems
Differential forms in Heisenberg groups and div-curl systems

Bruno Franchi , Universita di Bologna
In this talk we present a result proved in collaboration with Annalisa Baldi. We prove a family of inequalities for differential forms in Heisenberg groups (Rumin鈥檚 complex), that are the natural counterpart of a class of div-curl inequalities in de Rham鈥檚听 complex proved by Lanzani & Stein, Bourgain & Brezis.
