Minicorso: Isoperimetric inequality in CR manifolds in 3-D.

I plan to discuss the isoperimetric problem, in the Heisenberg space as well as CR 3-manifolds. I begin by reviewing the pseudohermitian geometry, the local geometry of a surface. The problem of Pansu. A new fourth order invariant called the Q-prime curvature, and its relation to the isoperimetric inequality.
