Abstract:

After a brief introduction of the concepts of Distributional Jacobians, we will define a Mumford-Shah energy for vector valued maps that generalizes the classical one. We will then introduce a family of approximating energy and prove a Gamma-convergence result, in the spirit of the previous works by Ambrosio and Tortorelli.
