Abstract
In this paper, our main purpose is studying the nonexistence of radial positive solutions for the
boundary-value problem:
where 
is an annulus in 
is a continuous nonlinear function and satisfies f(0) < 0 (the nonpositone case), f also has more than one zero.
Keywords: Nonpositone problem, radial positive solutions, nonexistence
