Analysis of a mathematical model with nonlinear susceptibles-guided interventions
Mathematical Biosciences and Engineering, 2019 In this paper, we considered a mathematical model describing the nonlinear susceptibles-guided vaccination and isolation strategies, incorporating the continuously saturated treatment. In this strategy, we find that the disease-free periodic solution can

Existence and regularity of time-periodic solutions to the three-dimensional Navier-Stokes equations [PDF]
, 2014 Existence, uniqueness, and regularity of time-periodic solutions to the Navier-Stokes equations in the three-dimensional whole-space are investigated. We consider the Navier-Stokes equations with a non-zero drift term corresponding to the physical model ...

Periods of solutions of periodic differential equations
Differential and Integral Equations, 2016 Smooth non-autonomous T-periodic differential equations x'(t)=f(t,x(t)) defined in \R\K^n, where \K is \R or \C and n 2 can have periodic solutions with any arbitrary period~S. We show that this is not the case when n=1. We prove that in the real C^1-setting the period of a non-constant periodic solution of the scalar differential equation is a divisor

Dynamic Complexity in a Prey-Predator Model with State-Dependent Impulsive Control Strategy
Complexity, 2020 In this paper, an ecological model described by a couple of state-dependent impulsive equations is studied analytically and numerically. The theoretical analysis suggests that there exists a semitrivial periodic solution under some conditions and it is ...

Analytical solutions of a particular Hill's differential system [PDF]
INCAS Bulletin, 2019 Consider a second order differential linear periodic equation. This equation is recast as a first-order homogeneous Hill’s system. For this system we obtain analytical solutions in explicit form. The first solution is a periodic function.

PERIODIC SOLUTION OF A MICRO-ELECTROMECHANICAL SYSTEM
Facta Universitatis, Series: Mechanical EngineeringThis paper examines the periodic motion of the micro-electro-mechanical system (MEMS), which is governed by a singularity that makes it challenging to find an exact solution and to understand its dynamical properties.
