Various specialized forms of the problem were solved, but it was only in 1930 that general solutions were found independently by Jesse Douglas and Tibor Rado . Their methods were quite different; Rado's work built on the previous work of Garnier and held only for Rectifiable simple closed curves, whereas Douglas used completely new ideas with his result holding for an arbitrary simple closed curve. Both relied on setting up minimization problems; Douglas minimized the now-named Douglas integral while Rado minimized the "energy". Douglas went on to be awarded the Fields Medal in 1936 for his efforts. The extension of the problem to higher Dimension s (that is, for -dimensional surfaces in -dimensional space) turns out to be much more difficult to study. Moreover, while the solutions to the original problem are always regular, it turns out that the solutions to the extended problem may have Singularities if . In the Hypersurface case where , singularities only occur for . To solve the extended problem, the Theory Of Perimeters ( De Giorgi ) for boundaries and the theory of Rectifiable Current s (Federer and Fleming) have been developed. REFERENCES |
