Method of functional parametrization for solving a semi-periodic initial problem for fourth-order partial differential equations

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2020
A semi-periodic initial boundary-value problem for a fourth-order system of partial differential equations is considered. Using the method of functional parametrization, an additional parameter is carried out and the studied problem is reduced to the ...

Solvability of a fourth order boundary value problem with periodic boundary conditions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
Fourth order boundary value problems arise in the study of the equilibrium of an elastaic beam under an external load. The author earlier investigated the existence and uniqueness of the solutions of the nonlinear analogues of fourth order boundary value

The Kuramoto–Sivashinsky equation. A Local Attractor Filled with Unstable Periodic Solutions

open access: yesМоделирование и анализ информационных систем, 2018
A periodic boundary value problem is considered for one version of the KuramotoSivashinsky equation, which is widely known in mathematical physics. Local bifurcations in a neighborhood of the spatially homogeneous equilibrium points in the case when they

Singularly perturbed higher order periodic boundary value problems

open access: yesJournal of Mathematical Analysis and Applications, 2004
Let \(n\), \(N\in\mathbb{N}\), \(n\geq 2\), \(N\geq 1\), \(T> 0\) and \(\mathbb{R}^+= (0,\infty)\). The authors consider the \(n\)th-order differential system in \(\mathbb{R}^N\) \[ x^{(n)}+ A_{n-1} x^{(n- 1)}+\cdots+ A_1x'+ A_0f(t, x)= e(t)\tag{1} \] together with the periodic boundary conditions \[ x(0)= x(T),\quad x'(0)= x'(T),\dots, x^{(n-1)}(0)= x^

On Antiperiodic Boundary Value Problems for Higher-Order Fractional Differential Equations

open access: yesAbstract and Applied Analysis, 2012
We study an antiperiodic boundary value problem of nonlinear fractional differential equations of order q∈(4,5]. Some existence results are obtained by applying some standard tools of fixed-point theory.

On periodic boundary value problem for the Sturm-Liouville operator

open access: yes, 2005
We consider the Sturm-Liouville operator Lu=u''-q(x)u with periodic or antiperiodic boundary conditions. It is shown that depending of Fourier coefficients of the potential q(x) the system of root functions may have or may not have the basis property ...
