In the present paper, we develop a septic B-spline method for solving a self-adjoint
singularly perturbed two-point boundary value problem. This method is applied directly to …

Fourth order eigenvalue problems with periodic and separated boundary conditions are
considered. One of the separated boundary conditions depends linearly on the eigenvalue …

In this paper, we find new canonical forms of self-adjoint boundary conditions for regular
differential operators of order two and four. In the second order case the new canonical form …

A regular fourth order differential equation which depends quadratically on the eigenvalue
parameter λ λ is considered with classes of separable boundary conditions, where exactly …

A regular fourth-order differential equation that depends quadratically on the eigenvalue
parameter $\lambda $ is considered with classes of separable boundary conditions …

Fourth order problems with the differential equation y (4)-(gy′)′= λ 2 y, where g∈ C 1 [0,
a] and a> 0, occur in engineering on stability of elastic rods. They occur as well in …

Asymptotics of the eigenvalues of a fourth order differential operator with eigenvalue dependent
and periodic boundary condition Page 1 Asymptotics of the eigenvalues of a fourth order …

Canonical forms of boundary conditions are important in the study of the eigenvalues of
boundary conditions and their numerical computations. The known canonical forms for self …

Fourth order problems, with the differential equation $ y^{(4)}-(gy')'=\lambda^ 2y $, where $
g\in C^ 1 [0, a] $ and $ a> 0$, occur in engineering on stability of elastic rods. They occur as …
