Abstract: In this paper, we study some systems of integral equations, including those related to HardyLittlewoodSobolev (HLS) inequalities. We prove that, under some integrability conditions, the positive regular solutions to the systems are radially symmetric and monotone about some point. In particular, we established the radial symmetry of the solutions to the EulerLagrange equations associated with the classical and weighted HardyLittlewoodSobolev inequality.
