weakly harmonic map from a two-dimensional domain is always smooth. The proof
is of a local nature and assumes that the Dirichlet energy is sufficiently
small; under this condition it is possible to re-write the harmonic map
equation using a suitably chosen frame which uncovers non-linearities with more
favourable regularity properties (so-called div-curl or Wente structures). We
will prove a global estimate for harmonic maps without assuming a small energy
bound, utilising a powerful theory introduced by T. Rivière. Along the way we
will highlight the relevance of Wente-type estimates in neighbouring areas of
geometric analysis, and hint as to why the analogous higher-dimensional global
estimate remains a challenging open problem. </span><span style="font-family:"Times New Roman",serif;background-image:initial;background-position:initial;background-size:initial;background-repeat:initial;background-origin:initial;background-clip:initial">This is a joint work
