Geometric Methods in PDE ́s: I.N.d.A.M. Meeting on the occasion of the 70 th birthday of Ermanno Lanconelli, Cortona, 27-31 maggio 2013,

The scope of this conference is to celebrate the 70th birthday of Ermanno Lanconelli and to bring together Italian and foreign Mathematicians to favour the discussion in the areas of research where Ermanno Lanconelli has been particularly active: - Second order linear and nonlinear partial differential equations with non-negative characteristic form; - Geometric problems related to the underlying algebraic, geometrical or topological structure; - Application to complex geometry and CR manifolds. These fields are the objects of active research and development, and possess a remarkable degree of interrelation in their pure and applied aspects.
