This is a survey article presenting mainly the results of A. R. Nahmod, A. Stefanov and K. Uhlenbeck [Commun. Pure Appl. Math. 56, No. 1, 114–151 (2003; Zbl 1028.58018)] and A. R. Nahmod, A. Stefanov, K. Uhlenbeck [Commun. Anal. Geom. 11, 49–83 (2003)]. The subject are Schrödinger maps and wave maps (which are two different hyperbolic versions of harmonic maps) from Minkowski space into compact Riemannian manifolds. The survey focusses on the results and stresses similarities in the methods used, including methods from harmonic analysis and gauge theory.
