Existence of nonconstant periodic solutions for p(t) $p(t)$-Laplacian Hamiltonian system

open access: yesBoundary Value Problems, 2019
The purpose of this paper is to consider the existence of periodic solutions for the p(t) $p(t)$-Laplacian Hamiltonian system. Some results are obtained by using the least action principle and the minimax methods.

Dynamics and stationary distribution of a stochastic SIRS epidemic model with a general incidence and immunity

open access: yesBoundary Value Problems, 2022
Infected individuals often obtain or lose immunity after recovery in medical studies. To solve the problem, this paper proposes a stochastic SIRS epidemic model with a general incidence rate and partial immunity. Through an appropriate Lyapunov function,

Symmetry approach in boundary value problems [PDF]

open access: yes, 1995
The problem of construction of the boundary conditions for nonlinear equations is considered compatible with their higher symmetries. Boundary conditions for the sine-Gordon, Jiber-Shabat and KdV equations are discussed.

Nonharmonic analysis of boundary value problems [PDF]

open access: yes, 2015
In this paper we develop the global symbolic calculus of pseudo-differential operators generated by a boundary value problem for a given (not necessarily self-adjoint or elliptic) differential operator.

Ground state solutions for Hamiltonian elliptic systems with super or asymptotically quadratic nonlinearity

open access: yesBoundary Value Problems, 2019
This article concerns the Hamiltonian elliptic system: {−Δφ+V(x)φ=Gψ(x,φ,ψ)in RN,−Δψ+V(x)ψ=Gφ(x,φ,ψ)in RN,φ,ψ∈H1(RN). $$ \textstyle\begin{cases} -\Delta \varphi +V(x)\varphi =G_{\psi }(x,\varphi ,\psi ) & \mbox{in } \mathbb {R}^{N}, \\ -\Delta \psi +V(x)\

The Existence of Countably Many Positive Solutions for Nonlinear nth-Order Three-Point Boundary Value Problems

open access: yesBoundary Value Problems, 2009
We consider the existence of countably many positive solutions for nonlinear nth-order three-point boundary value problem u(n)(t)+a(t)f(u(t))=0, t∈(0,1), u(0)=αu(η), u′(0)=⋯=u(n−2)(0)=0, u(1)=βu(η),

Global dynamics for an SVEIR epidemic model with diffusion and nonlinear incidence rate

open access: yesBoundary Value Problems, 2022
In this paper, we investigate an SVEIR epidemic model with reaction–diffusion and nonlinear incidence. We establish the well-posedness of the solutions and the basic reproduction number R 0 $\mathfrak{R}_{0}$ .
