On the Use of Discrete Fourier Transform for Solving Biperiodic Boundary Value Problem of Biharmonic Equation in the Unit Rectangle [PDF]
This note is addressed to solving biperiodic boundary value problem of biharmonic equation in the unit rectangle. First, we describe the necessary tools, which is discrete Fourier trans- form for one dimensional periodic sequence, and then extended the ...

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

Oscillatory processes in the theory of particulate formation in supersaturated chemical solutions [PDF]
We study a nonlinear problem which occurs in the theory of particulate formation in supersaturated chemical solutions. Mathematically, the problem involves the bifurcation of time-periodic solutions in an initial-boundary value problem involving a ...

Singularly perturbed higher order periodic boundary value problems
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
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.
