Tangent cones to two-dimensional area-minimizing integral currents are unique
The author proves uniqueness of tangent cones for two dimensional integral currents in \(R^ n\). He reduces the problem to an ''epiperimetric'' inequality which is proved by constructing a comparison surface from the graph of a multiple-valued harmonic function, whose area he estimates in terms of the Fourier series of its boundary values.
