具有高斯界的退化椭圆算子的Kato问题的解

The solution of the Kato problem for degenerate elliptic operators with Gaussian bounds

D. Cruz-Uribe, C. Rios

摘要:

证明了R^n中退化椭圆算子的Kato猜想。更精确地说,我们考虑散度型算子L_w = -1/wdiv(wA)grad,其中w是MuckenhouptA_2权,A是有界一致椭圆的复值n × n矩阵.我们证明了,如果相应的半群满足高斯上界,那么Kato平方根估计成立。

英文摘要:

We prove the Kato conjecture for degenerate elliptic operators in R^n. More precisely, we consider the divergence form operator L_w = -1/w div (wA) grad, where w is a Muckenhoupt A_2 weight and A is a complex valued n x n matrix which is bounded and uniformly elliptic. We show that if the associated semigroup satisfies Gaussian upper bounds, then the Kato square root estimate holds.
