This paper concerns local gradient estimates to solutions of general conformally invariant fully nonlinear elliptic equations of second order.
Derivative estimates of solutions of elliptic systems in narrow regions
In this paper we establish local derivative estimates for solutions to a class of elliptic systems arising from studies of fiber-reinforced composite materials. From the structure of the composite,… Expand
