TWO-POINT BOUNDARY VALUE PROBLEMS OF FOURTH ORDER WITH POSITIVE GREBi'S FUIICTIONS
ثبت نشده
چکیده
There are derived sufficient conditions for the posltivity of Green's function of two-point boundary value problems of the fourth order. The results are gained by applying a theorem on Inverse-monoton o operators In partially ordered spaces. In the case of an example (beam on elastic support), the derived conditions are also necessary.
