Title: Wilson loops, amplitudes and anomalies in N=4 SYM

Abstract: First I will briefly review a generalization of chiral Wilson loops dual to amplitudes, to non-chiral Wilson loops in full N=4 superspace, which is expected to be exactly Yangian invariant. Then I will discuss the related idea of reconstructing amplitudes in N=4 SYM by the Yangian "anomalies", and a new proposal of all-loop recursion relation for the anomalies, directly in terms of infrared-safe quantities, such as remainder and ratio functions.
