From the authors’ abstract: Space-like constant mean curvature (CMC) surfaces in Minkowski three-space $$\mathbb L^3$$ have an infinite dimensional generalized Weierstrass representation. This is analogous to that given by Dorfmeister, Pedit and Wu for CMC surfaces in Euclidean space, replacing the group $$\text{SU}(2)$$ with $$\text{SU}(1,1)$$. The non-compactness of the latter group, however, means that the Iwasawa decomposition of the loop group, used to construct the surfaces, is not global. The construction is described here, with an emphasis on the difference from the Euclidean case.
