Journal of Applied Mathematics, Volume 2022, Issue 1, 2022., 2022 Migration of pollutant particles into subsurface water reservoirs through point sources is largely involved mixing processes within the system of water flow. Possible potential sources of pollution to these point sources include municipal wastes, septic loads, landfills, uncontrolled hazardous wastes, and sewage storage tanks.

Dichotomy Condition and Periodic Solutions for Two Nonlinear Neutral Systems
Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022 In this article, we consider two nonlinear neutral systems with multiple delays. Our main tool here is to use dichotomy theory to construct an implicit solution for these two systems. Utilizing Krasnoselskii’s fixed point theorem, we obtain sufficient criteria for the existence of periodic solutions, as well as for the uniqueness of solutions. The main

Dynamics in a Nonautonomous Nicholson‐Type Delay System
Journal of Mathematics, Volume 2021, Issue 1, 2021., 2021 A kind of Nicholson‐type delay system is considered. Several conditions on the ultimate boundedness, extinction, permanence, periodic solution, and global attractivity of the system are established by employing the inequality techniques and comparison method and constructing suitable Lyapunov functional.

Periodic Oscillating Dynamics for a Delayed Nicholson‐Type Model with Harvesting Terms
Mathematical Problems in Engineering, Volume 2021, Issue 1, 2021., 2021 In this manuscript, a delayed Nicholson‐type model with linear harvesting terms is investigated. Applying coincidence degree theory, we establish a sufficient condition which guarantees the existence of positive periodic solutions for the delayed Nicholson‐type model.

Journal of Function Spaces, Volume 2021, Issue 1, 2021., 2021 A linearized numerical scheme is proposed to solve the nonlinear time‐fractional parabolic problems with time delay. The scheme is based on the standard Galerkin finite element method in the spatial direction, the fractional Crank‐Nicolson method, and extrapolation methods in the temporal direction.

Global asymptotic stability of a scalar delay Nicholson's blowflies equation in periodic environment
Electronic Journal of Qualitative Theory of Differential Equations, 2022 This paper is considered with a scalar delay Nicholson's blowflies equation in periodic environments. By taking advantage of some novel differential inequality techniques and the fluctuation lemma, we set up the sharp condition to characterize the global

Global existence of positive periodic solutions of a general differential equation with neutral type
Advances in Difference Equations, 2021 In this paper, the dynamics of a general differential equation with neutral type are investigated. Under certain assumptions, the stability of positive equilibrium and the existence of Hopf bifurcation are obtained by analyzing the distribution of ...
