Abstract.
In the seminar I will illustrate several notions of (modulus of) gradient arising in the theory of Sobolev classes in metric measure spaces. A byproduct of the recent work with G.Savare' and N.Gigli is the equivalence of these notions, obtained via optimal transportation tools. The open case of W{1,1} or BV maps will also be illustrated.
