标题： Impact of Yves Meyer's work on Kato's conjecture

摘要： 我们讨论Yves Meyer与Raphy Coifman在七十年代关于Calderón计划和具有最小平滑性的奇异积分的工作，不仅为解决椭圆算子平方根的Kato猜想铺平了道路，也推动了在粗糙域上带有粗糙系数的椭圆和抛物边界值问题的重大发展。 显示英文摘要

摘要： We discuss how the works of Yves Meyer, together with Raphy Coifman, on Calder{\'o}n's program and singular integrals with minimal smoothness in the seventies, paved the way not only to a solution to Kato's conjecture for square roots of elliptic operators, but also to major developments in elliptic and parabolic boundary value problems with rough coefficients on rough domains.
