Course description

From the book  A course in Minimal Surfaces by T.H. Colding and W.P. Minicozzi II:

"Minimal surfaces date back to Euler and Lagrange and the beginning of the calculus of variations. Many of the techniques developed have played key roles in geometry and partial differential equations. Examples include monotonicity and tangent cone analysis originating in the regularity theory for minimal surfaces, estimates for nonlinear equations based on the maximum principle arising in Bernstein's classical work, and even Lebesgue's definition of the integral that he developed in his thesis on the Plateau problem for minimal surfaces."

From the Introduction of Minimal Surfaces and Functions of Bounded Variation by E. Giusti:

"The problem of finding minimal surfaces, i.e. of finding the surface of least area among those bounded by a given curve, was one of the first considered after the foundation of the calculus of variations, and is one which received a satisfactory solution only in recent years. Called the problem of Plateau, after the blind physicist who did beautiful experiments with soap films and bubbles, it has resisted the efforts of many mathematicians for more than a century. It was only in the thirties that a solution was given to the problem of Plateau in 3-dimensional Euclidean space, with the papers of Douglas and Rado."

This course gives an introduction to the theory of minimal surfaces. Some topics that might be discussed:

Geometry of submanifolds of Rn, Riemannian metrics, mean curvature of submanifolds
First variation of area/volume
Parametric and non-parametric minimal surfaces, examples
Bernstein's theorem
Plateau's problem
Functions of bounded variation and existence of minimal hypersurfaces in higher dimensions

Exams

The course can be passed by an exam or by solving home work problems and writing an essay.
