Grades are submitted. There were some fantastic papers. Popular were
the Moebius strip, ruled surfaces, minimal surfaces (careful proof that H=0 gives
minimal surfaces), proof of Fenchel's theorem (about total curvature)
Black hole solutions to the Einstein equations (like the Kerr solution).
More samples: detailed proof of Hopf Rynov, some information geometry
like metrics on manifolds of probability distributions, the isoperimetric
inequality or the Jordan curve theorem.
Since the camera shifted, Hugo to the very right was not on the picture.
But Hugo exists.
