摘　　要：This paper consider a class of quasi-linear multi-point boundary value problem whose nonlinear term is allowed to change sign and depends on the first order deriva-tive. By a new fixed point theorem,sufficient conditions for the existence of positive solutions are established.This paper consider a class of quasi-linear multi-point boundary value problem whose nonlinear term is allowed to change sign and depends on the first order deriva-tive.
