Abstract: Abstract Let R n(n = 3, 4, 5, …) he the n-dimensional Euclidean space, r(x, y). the distance from x∈R n to y∈R n k an integer with 1≦k≦n−1, F⊂R n a bounded k-dimensional manifold (the assumptions on F will be fixed later), ϕ a mass distribution on F, i.e., ϕ is a finite signed measure, defined, on σ-algebra of subsets of F which contains all Borel subsets of F. Then the k-dimensional potential 1.1 $${\rm u(x) = \int\limits_F {r^{2 - n} (x,y)d\varphi }} $$ is a harmonic in R n−F.
