Existence and Multiplicity of Weak Solutions for a Neumann Elliptic Problem with -Laplacian
We are interested in the existence of multiple weak solutions for the Neumann elliptic problem involving the anisotropic -Laplacian operator, on a bounded domain with smooth boundary.

Dynamics of almost periodic solutions for a discrete Fox harvesting model with feedback control
We consider the following discrete Fox harvesting model with feedback control of the form {x(n+1)=x(n)exp{β(n)lnr(K(n)x(n))−α(n)−γ(n)u(n)},Δu(n)=−μ(n)u(n)+ν(n)x(n).

Analytic Study on Hilfer Fractional Langevin Equations with Impulses
In this paper, we find a solution of a new type of Langevin equation involving Hilfer fractional derivatives with impulsive effect. We formulate sufficient conditions for the existence and uniqueness of solutions.

Asymptotically almost periodic solution to a class of Volterra difference equations
This paper is concerned with an asymptotically almost periodic solution to a class of Volterra-type difference equations. We establish a compactness criterion for the sets of asymptotically almost periodic sequences.

On almost automorphic solutions of linear operational‐differential equations
We prove almost periodicity and almost automorphy of bounded solutions of linear differential equations x′(t) = Ax(t) + f(t) for some class of linear operators acting in a Banach space.

Let u be a given bounded uniformly continuous mild solution of a higher‐order abstract functional differential equation of delay or advance type. We give a so‐called Massera‐type criterion for the existence of a mild solution, which is a “spectral component” of u with spectrum similar to the one of the forcing term f.

On almost periodic solutions of the differential equation x″(t) = Ax(t) in Hilbert spaces
We prove almost periodicity of solutions of the equation x″(t) = Ax(t) when the linear operator A satisfies an inequality of the form Re(Ax, x) ≥ 0.

Periodic solution for ϕ-Laplacian neutral differential equation
This paper is devoted to the existence of a periodic solution for ϕ-Laplacian neutral differential equation as follows (ϕ(x(t)−cx(t−τ))′)′=f(t,x(t),x′(t)).$$\begin{array}{} (\phi(x(t)-cx(t-\tau))')'=f(t,x(t),x'(t)). \end{array}$$
