  This is a talk delivered at the Workshop on Quantum Fields and Strings of the
2014 Corfu Summer Institute. We discuss how giant magnons emerge in the context
of the AdS5/CFT4 correspondence as the gravity duals of N = 4 super Yang-Mills
magnon excitations. Then we present a new analytic expression for the
dispersion relation of classical finite-size giant magnons with Lambert's
W-function.
