“…Example 4.5. Consider the following fourth-order Sturm-Liouville problem related to mechanicals non-linear systems identification [7], [10], [14]    y (4) (x) − 2αx 2 y − 4αxy + (α 2 x 4 − 2α)y = λy(x), x ∈ (0, 5), y(0) = y (0) = 0, y(5) = y (5) = 0. x 13 λα 2 − 119 18532800…”

“…However many important phenomena occurring in various fields of science are described mathematically by highorder Sturm-Liouville problems. For example, the free vibration analysis of beam structures [6], [7], [8] is governed by a fourth-order Sturm-Liouville problem, and it is known that when a layer of fluid is heated from below and is subject to the action of rotation, instability may set as overstability, this instability my be modelled by a eighth-order Sturm-Liouville boundary value problem with appropriate boundary conditions specified. It may be noted that, when instability sets as ordinary convection, the marginal state will be characterized by sixth-order Sturm-Liouville boundary value problem [9], [10], [11], [12].…”

“…Slightly fewer techniques are available for the direct eigenvalue problem of case m = 2 known as fourth-order Sturm-Liouville problem (FSLP). For example, Adomian decomposition method (ADM) [16], Chebyshev spectral collocation method (CSCM) [17], Homotopy Perturbation Method (HPM) [11], homotopy analysis method (HAM) [18], Differential quadrature method (DQM) and Boubaker polynomials expansion scheme (BPES) [19], Chebychev method (CM) [20], Spectral parameter power series (SPPS) [21], Chebyshev differentiation matrices (CDM) [22], variational iteration method (VIM) [23], Matrix methods (MM) [24], and Lie Group method [25] are the prominent techniques available.…”

“…On the other hand, Pseudospectral methods are a class of numerical methods which were introduced in 1970s [6,7,26]. Their application for solving engineering problems has become popular due to their computational feasibility and efficiency [12,27,31,32,34,35]. In the pseudospectral method, the unknown solution is expanded as a global polynomial interpolant based on some suitable collocation points.…”
