$L^2$-boundedness of gradients of single layer potentials for elliptic operators with coefficients of Dini mean oscillation-type

Alejandro Molero, Mihalis Mourgoglou, Carmelo Puliatti +1

We consider a uniformly elliptic operator $L_A$ in divergence form associated with an $(n+1)\times (n+1)$-matrix $A$ with real, merely bounded, and possibly non-symmetric coefficien…
