Yasunori Maekawa, Hideyuki Miura

摘要:

考虑$\R^{d+1}$中系数与一个变量无关的散度型二阶一致椭圆算子.在利普希茨条件下,我们刻画了Poisson算子和Dirichlet-Neumann映射在索伯列夫空间$s\in [0,1]$中的定义域.此外,我们还证明了一个因子分解公式的椭圆算子的泊松算子。

英文摘要:

We consider second order uniformly elliptic operators of divergence form in $\R^{d+1}$ whose coefficients are independent of one variable. Under the Lipschitz condition on the coefficients we characterize the domain of the Poisson operators and the Dirichlet-Neumann maps in the Sobolev space $H^s(\R^d)$ for each $s\in [0,1]$. Moreover, we also show a factorization formula for the elliptic operator in terms of the Poisson operator.
