Abstract : The differential equation considered in the paper is Phi' = f(x, Phi) psi (x) with conditions Phi (0) = y sub o, R Phi' (R)  Phi (R) = q for 0 < or x < = R, where yo,R,q are given real numbers, y sub o > O, R > O. The solution sought, phi(x), is to be nonnegative. A number of conditions are imposed on f(x,phi) and psi. Problems of this type are encountered in the statistical theory of the atom, and these conditions follow naturally from the physical setting of the problems. Continuous dependence of the interval of existence of the solution and the continuous dependence of the solution itself on the boundary values are established. (Author)
