摘要：
It is proved that the solutions of the equation Delta u+u = 0 are characterized by vanishing of integrals over all balls in R(n) with radii belonging to the zero set of the Bessel function J(n/2). This result enables us to get a solution of the Pompeiu problem on the class of functions of slow growth in terms of approximation in L(R(n)) by linear combinations with special radii.
