We study the existence of multiple positive solutions for nth-order multipoint boundary value problem. u(n)(t)+a(t)f(u(t))=0, t∈(0,1), u(j-1)(0)=0(j=1,2,…,n-1), u(1)=∑i=1mαiu(ηi), where n≥2, 0<η1<η2<⋯<ηm<1, αi>0,i=1,2,…,m. We obtained the existence of multiple positive solutions by applying the fixed point theorems of cone expansion and compression of norm type and Leggett-Williams fixed-point theorem. The results obtained in this paper are different from those in the literature.
