Explore the fascinating world of zero mean curvature surfaces in this comprehensive lecture from the International Centre for Theoretical Sciences' online discussion meeting. Delve into topics such as volume of hypersurfaces, stability of minimal surfaces, the Bernstein problem, and Weierstrass representation. Examine various examples of minimal surfaces, including Scherk's surfaces, singly, doubly, and triply periodic surfaces, and nonorientable surfaces like the Möbius strip and Klein bottle. Learn about the Gauss map, the Osserman inequality, and engage with complex mathematical concepts in this in-depth exploration of geometric surfaces in Euclidean and Lorentz-Minkowski 3-space.
