Abstract: We consider problems of the form

$(\phi(u'))' = f(t, u, u'), t \in (0, 1)$;


under the three point boundary condition

$u'(0) = 0, u(n) = u(1);$


where $n \in$ (0, 1) is given. This problem is at resonance. Three-point boundary value problems at resonance have been studied in several papers, we present here some new result as well as generalizations of some results valid for particular forms of the operator -$(\phi(u'))'.

Keywords:  multipoint, boundary value problem, non homogeneous operator.
