DESCRIPTION:Title: <a href="https://researchseminars.org/talk/BOWL/10/">A 
 Bernstein-type theorem for two-valued minimal graphs in dimension four</a>
 \nby Fritz Hiesmayr (UCL) as part of B.O.W.L Geometry Seminar\n\n\nAbstrac
 t\nThe Bernstein theorem is a classical result for minimal graphs. It stat
 es that\na globally defined solution of the minimal surface equation on $\
 \mathbb{R}^n$ must be linear\,\nprovided the dimension is small enough. We
  present an analogous theorem for\ntwo-valued minimal graphs\, valid in di
 mension four. By definition two-valued\nfunctions take values in the unord
 ered pairs of real numbers\; they arise as the\nlocal model of branch poin
 t singularities. The plan is to juxtapose this with the\nclassical single-
 valued theory\, and explain where some of the difficulties emerge\nin the 
 two-valued setting.\n
