Boundary value problems for second order elliptic operators with complex coefficients
Martin Dindoš, Jill Pipher
The theory of second order complex coefficient operators of the form $\mathcal{L}=\mbox{div} A(x)\nabla$ has recently been developed under the assumption of -ellipticity. In par…

Perturbation theory for solutions to second order elliptic operators with complex coefficients and the Dirichlet problem
Martin Dindoš, Jill Pipher
We establish a Dahlberg-type perturbation theorem for second order divergence form elliptic operators with complex coefficients. In our previous paper, we showed the following resu…

Commutators of multi-parameter flag singular integrals and applications
Xuan Thinh Duong, Ji Li, Yumeng Ou +2
We introduce the iterated commutator for the Riesz transforms in the multi-parameter flag setting, and prove the upper bound of this commutator with respect to the symbol in th…
