Almost periodic solution of a discrete competitive system with delays and feedback controls

Open Mathematics, 2019
A discrete nonlinear almost periodic multispecies competitive system with delays and feedback controls is proposed and investigated. We obtain sufficient conditions to ensure the permanence of the system.

Ambrosetti–Prodi Periodic Problem Under Local Coercivity Conditions

Advanced Nonlinear Studies, 2018
In this paper we focus on the periodic boundary value problem associated with the Liénard differential equation x′′+f⁢(x)⁢x′+g⁢(t,x)=s{x^{\prime\prime}+f(x)x^{\prime}+g(t,x)=s}, where s is a real parameter, f and g are continuous functions and g is T ...

Pseudo S-asymptotically Bloch type periodicity with applications to partial stochastic neutral evolution equations [PDF]

Arab Journal of Mathematical Sciences
PurposeThis paper introduces the concept of (µ, ν)-pseudo S-asymptotically Bloch type (ω, k)- periodic functions, aiming to extend the framework of periodicity in stochastic analysis and to investigate their role in neutral partial stochastic ...

Non-hyperbolic P-Invariant Closed Characteristics on Partially Symmetric Compact Convex Hypersurfaces

Advanced Nonlinear Studies, 2018
Let n≥2{n\geq 2} be an integer, P=diag⁢(-In-κ,Iκ,-In-κ,Iκ){P=\mathrm{diag}(-I_{n-\kappa},I_{\kappa},-I_{n-\kappa},I_{\kappa})} for some integer κ∈[0,n]{\kappa\in[0,n]}, and let Σ⊂ℝ2⁢n{\Sigma\subset{\mathbb{R}}^{2n}} be a partially symmetric compact ...

Periodic Impact Motions at Resonance of a Particle Bouncing on Spheres and Cylinders

Advanced Nonlinear Studies, 2017
We investigate the existence of periodic trajectories of a particle, subject to a central force, which can hit a sphere or a cylinder. We will also provide a Landesman–Lazer-type condition in the case of a nonlinearity satisfying a double resonance ...

One-dimensional singular problems involving the p-Laplacian and nonlinearities indefinite in sign

Advances in Nonlinear Analysis, 2016
Let Ω be a bounded open interval, let p>1${p>1}$ and γ>0${\gamma>0}$, and let m:Ω→ℝ${m:\Omega\rightarrow\mathbb{R}}$ be a function that may change sign in Ω.
