【 摘 要 】
In this paper, by introducing a new operator, improving and generating a p-Laplace operator for some p > 1, we study the existence of countably many positive solutions for nonlinear boundary value problems on the half-line (phi(u '))' + a(t) f (u(t)) = 0, 0 < t < +infinity. u(0) = Sigma(m-2)(i=1) alpha(i)u(xi(i)). u '(infinity) = 0. where phi : R -> R is the increasing hemeomorphism and positive homomorphism and phi(0) = 0. We show the sufficient conditons for the existence of countably many positive solutions by using the fixed-point index theory and a new fixed-point theorem in cones.
