By using a fixed point theorem of mixed monotone operators in cone, this paper studied a fourth-order nonlinear singular boundary value problem, namely a class of elastic beam equation.
This paper discuss the locally topological structure of higher ordersingularpoint for the plane cubic system in the first critical case and give a criterion by the coefficients of polynomials.
