Abstract

Let () be a bounded domain, and let be the distance to . In this paper, we study positive solutions of the equation in , where , and is a continuous, nondecreasing function on . We prove that if satisfies a singular integral condition, then there exists a unique solution of with a prescribed boundary datum . When with , we show that equation admits a critical exponent (depending only on and ). In the subcritical case, namely , we establish some a priori estimates and provide a description of solutions with an isolated singularity on . In the supercritical case, i.e., , we demonstrate a removability result in terms of Bessel capacities.
