在R^n中的有界区域Ω中,考虑双特征Beltrami方程组.证明了双特征Beltrami方程组的广义解是有限伸张映射,并使能量泛函达到极小.
The Beltrami system with double characteristic matrices in high dimensional domain Ω of R^n was considered in this paper. It is proved that the generalized solutoins of Beltrami system with double characteristic matrices are mappings with finite distortion,and attains its minimal value for the energy functonal.
