Small $A_{\infty }$ results for Dahlberg-Kenig-Pipher operators in sets with uniformly rectifiable boundaries

Guy David, Linhan Li, Svitlana Mayboroda

In the present paper, we consider elliptic operators $L=-\text{div}(A\nabla )$ in a domain bounded by a chord-arc surface $\Gamma$ with small enough constant, and whose coefficients $A…
