We study the uniqueness of positive radial solutions to the Dirichlet boundary value problem for the semilinear elliptic equation u + f( | x | , u) = 0 in a finite ball or annulus in R n, n 3. Applying our main results to the cases when f is independent of t, or f is of the form K(t)u p, we can establish some earlier known results and obtain some new results in an easier and unified approach.
