Existence of multiple solutions for a third-order three-point regular boundary value problem Martin Šenkyřík — 1994 Mathematica Bohemica In the paper we prove an Ambrosetti-Prodi type result for solutions u of the third-order nonlinear differential equation, satisfying u ' ( 0 ) = u ' ( 1 ) = u ( η ) = 0 , 0 ≤ η ≤ 1 .
