We prove here the existence of a bounded, radial solution in unbounded domain of the nonlinear elliptic problem ?u = f(||x||,u) for ||x||> 1, x ∈ Rn u(x)=0 for ||x||=1 under some asymptotic and sign condition on f. Under stronger assumptions it is proved that this solution must be of constant sign. The existence of radial solutions, vanishing at ? , of some semilinear equation is also established here.
