    Multiplicity of concave and monotone positive solutions for nonlinear fourth-order ordinary differential equations (English)
    0 references
    The author proves the existence and multiplicity of positive solutions of a fourth-order multi-point boundary value problem with nonlinearity depending on all order derivatives. The proof of the main results is based upon the constructing the associated Green function and a fixed point theorem.
