The Rumin algebra of a contact manifold
Speaker: Jeffrey Case, Penn State
Abstract: On a contact manifold, the Rumin complex is a differential complex which computes de Rham cohomology. In this talk, I show that the Rumin complex is a deformation retract of the de Rham complex, thereby recovering the $A_\infty$-structure on the former which was previously defined by ad hoc methods. If time allows, I will also discuss some possible applications to formality.
