We consider the nonlinear Sturm-Liouville boundary value problem {(Lu)(t) = lambda a(t)f(u(t)), 0 < t < 1, R-i(u)= alpha(i)u(0) + beta(1)u'(0) = 0, R-2(u) = alpha(2)u(1) + beta(2)u'(1) = 0, where L is the linear Sturm-Liouville operator (Lu)(t) = -(p(t)u' (t))' + q(t)u(t). We obtain a global bifurcation result for a related bifurcation problem. We then use this to obtain multiple (at least eight) solutions of the Sturm-Liouville problem having specified nodal properties. (C) 2010 Elsevier B.V. All rights reserved.
