ABSTRACT: I will discuss the relaxed Dirichlet energy for maps from B3 into S2 (definitions, meaning, etc... ), treating the regularity theory in particular. This field contains several long standing open questions. I will present a recent result which gives us a better understanding of the minimizers of this energy, and casts even more open questions.
