Positive radial solutions of certain semilinear elliptic equations in annular domains

In this paper it is established the existence, behaviour and approximation of positive radially symetric solutions of semilinear elliptic equation in an annulus, when the corresponding sufficient conditions are satisfied. The errors of the approximation are defined by the functions which can be sufficiently small.
