It shows that the frequency function must be of value k/2 for some nonnegative integer k. Futhermore, by looking at the blowing-up functions, we characterize the local behavior of the original Dirichlet minimizing function.21 pagesAnalysis of PDEsOptimization and Control49Q20A Theorem on Frequency Function for Multiple-Valued Dirichlet Minimizing Functionstext
