The periodic boundary value problems (1).
Boundary Value Problems (Impact Factor 1.05).
The singular boundary value problems (1.1).
Such boundary value problems are generally nonselfadjoint.
When (k=0), the three-point boundary value problems degenerate to two-point boundary value problems.
Many authors considered the biharmonic boundary value problem or the fourth-order elliptic boundary value problems.
Recently, many researchers pay more attention to the impulsive boundary value problems, such as Dirichlet boundary value problem, periodic boundary value problem, two point boundary value problem and so on (see for example, [9], [10] and references therein).
Based on them, the local existence-uniqueness of positive solutions for nonlinear boundary value problems which include Neumann boundary value problems, three-point boundary value problems and elliptic boundary value problems for Lane-Emden-Fowler equations was proved.
Applications to initial value and boundary value problems are included.
Recently, using the RKM, the authors discussed two-point boundary value problems and periodic boundary value problems.
