We improve an estimate given by Acerbi and Dal Maso in 1994, concerning the area of the graph of a singular map from the disk of ℝ 2 into ℝ 2, taking only three values, and jumping on three half-lines meeting at the origin in a triple junction.

Abstract
We improve an estimate given by Acerbi and Dal Maso in 1994, concerning the area of the graph of a singular map from the disk of ℝ 2 into ℝ 2, taking only three values, and jumping on three half-lines meeting at the origin in a triple junction.File in questo prodotto:
