Abstract: | Abstract] In this paper, by using the fixed point method, we get the existence of positive solutions to the three-point boundary value problem for a second order differential equation system in some weak conditions -/μ^N=f(t,υ),t∈(O,1)-υ^=g(t,υ),t∈(0,1),μ^1(0)=υ'(0)=0,μ(1)=aμ(η),υ(1)=υ'(η) ∈(0,1),0〈υ〈1 |
