Abstract.

We investigate an integral equation with Bessel potential in ℝn+ and prove that every positive solution of the integral equation is rotationally symmetric about some line parallel to the -axis. Furthermore, we consider an overdetermined problem of the same integral equation in a cylinder type domain and obtain the symmetry of both domains and solutions, where is a bounded domain with .
