Calibrated integral currents are a particular class of mass-minimizers and as such provide interesting explicit examples of solutions to Plateau’s problem. Their role goes however much beyond that: they naturally appear when dealing with several geometric questions. After a brief introduction to integral currents and calibrations, we will overview some geometric problems where the smoothness of calibrated currents plays a key role and present the optimal regularity result for Special Lagrangian 3-dimensional cones (joint work with T. Rivière).
