椭圆系统与材料互穿

Elliptic systems and material interpenetration

Giovanni Alessandrini, Vincenzo Nesi

摘要:

本文对二阶线性二乘二系统进行了分类,并证明了平面调和映射的两个基本定理:Rado '-Kneser-Choquet定理和H。路易定理,保持。它们是那些直到变量的线性变量变换都可以用同一个算子在两个对角块上写成对角形式的函数。特别是,我们证明了上述定理不能扩展到解决方案的拉梅'系统的弹性,或椭圆系统的对角形式,即使只是略有不同的运营商的两个组件。

英文摘要:

We classify the second order, linear, two by two systems for which the two fundamental theorems for planar harmonic mappings, the Rado'-Kneser-Choquet Theorem and the H. Lewy Theorem, hold. They are those which, up to a linear change of variable, can be written in diagonal form with the same operator on both diagonal blocks. In particular, we prove that the aforementioned Theorems cannot be extended to solutions of either the Lame' system of elasticity, or of elliptic systems in diagonal form, even with just slightly different operators for the two components.
