Let a E C[0.1], b E C ([0.1], (-∞, 0)). Let φ1(t) be the unique solution of the linear boundrary value problem u"(t)+a(t)u'(t)+b(t)u(t)=0, t e (0.1), u(0)=0, u(1)=1. We study the multiplicity of positive solutions for the m-point boundary value problems of Dirichlet type u" +a(t)u' +b(t)u+g(t)f(u)=0, u(0)=0, u(1)-m-2Σi=1 a1u(ξi)=0, where ξi Σ(0, 1) and ai e (0, ∞), ie{1, …, m-2}, are given constants satisfying Σm-2, I=1 aiф1(ξi)<1. The methods employed are fixed-point index theory.
