Title of talks

・Miyuki Koiso (Kyushu University)

Title: Variational problems for surfaces


・Jaigyoung Choe (Korea Institute for Advanced Study)

Title: Existence of four free boundary minimal annuli in a tetrahedron

Abstract: Please click the mark "∨" on the right.

Abstract: It will be shown that for any tetrahedron T with acute dihedral angles there exist four embedded minimal annuli in T which are perpendicular to the boundary of T. It will be also proved that every Platonic solid contains five types of free boundary embedded minimal surfaces of genus zero.

・Atsufumi Honda (Yokohama National University)

Title: Singularities and type-changes of spacelike CMC surfaces


・Yu Kawakami (Kanazawa University) & Mototsugu Watanabe (Kanazawa University)

Title: Recent advances in value distribution of the Gauss map of complete minimal surfaces


・Nobumitsu Nakauchi (Yamaguchi University)

Title: A variational problem on conformality of maps and related problems


・Bennett Palmer (Idaho State University)

Title: Elastic surfaces with elastic boundaries

・Paolo Piccione (University of São Paulo)

Title: Minimal 2-spheres in ellipsoids via global bifurcation theory

Abstract: Please click the mark "∨" on the right.

Abstract: I will give an overview of classical results in variational Bifurcation Theory, present some applications to geometric variational problems, and discuss a concrete problem concerning the multiplicity of minimal 2-spheres inside sufficiently elongated ellipsoids.

・Toshihiro Shoda (Kansai University)

Title: On the non-existence of new families of triply periodic minimal surfaces


・Masaaki Umehara (Tokyo Institute of Technology)

Title: Null hypersurfaces as wave fronts in Lorentz-Minkowski space


・Kotaro Yamada (Tokyo Institute of Technology)

Title: Line theorems for zero mean curvature hypersurfaces in Lorentzian manifolds
