该文引入一类新的函数空间, 并借助于此空间, 研究了 A -调和方程很弱解的弱单调性, 并得到了空间Beltrami方程组弱解分量函数的弱单调性.
A new class of function space is introduced. The weak monotonicity of very weak solutions of A-harmonic equation is studied by using this function class. The weak monotonicity for component functions of weak solutions of Beltrami system in space is derived.
