Abstract:
In 1930, Douglas and Rado solved the Plateau's problem: Given a simple closed Jordan curve, does there exist a soap film (2D surface) that fills in the curve? Later on Courant (1936) found a simplified approach by modifying their methods. This presentation will start from discussing why the problem is hard and based on Courant's method, tries to suggest a way to get started on solving this problem. The second part outlines the key ingredients in the proof. Time permitting, the last part mentions its connections to the isoperimetric inequality, perhaps also the systolic inequality, the scalar curvature and threemanifold theory.
