Infinitely many periodic solutions for a class of fractional Kirchhoff problems
, 2019 We prove the existence of infinitely many nontrivial weak periodic solutions for a class of fractional Kirchhoff problems driven by a relativistic Schr\"odinger operator with periodic boundary conditions and involving different types of ...

Delay-induced patterns in a two-dimensional lattice of coupled oscillators [PDF]
, 2014 We show how a variety of stable spatio-temporal periodic patterns can be created in 2D-lattices of coupled oscillators with non-homogeneous coupling delays.

Multiple periodic solutions to a class of nonautonomous second-order delay differential equation
Boundary Value Problems, 2013 The existence of the nontrivial periodic solutions for nonautonomous second-order delay differential equation x″(t)+λx(t)=−f(t,x(t),x(t−τ)) is investigated, where λ>π2/τ2, τ>0, f∈C1(R×R2,R).

Forced Fermi-Pasta-Ulam lattice maps
, 2013 We prove existence and uniqueness results for periodic and quasiperiodic travelling waves of Fermi-Pasta-Ulam (FPU) type lattice maps. We also study quasiperiodic solutions of difference equations on Banach algebras as a natural generalizations of the ...

The dynamical analysis of a nonlocal predator–prey model with cannibalism
European Journal of Applied MathematicsCannibalism is often an extreme interaction in the animal species to quell competition for limited resources. To model this critical factor, we improve the predator–prey model with nonlocal competition effect by incorporating the cannibalism term, and ...

Existence of solutions and stability for impulsive neutral stochastic functional differential equations [PDF]
, 2019 In this paper we prove some results on the existence of solutions and the mean square asymptotic stability for a class of impulsive neutral stochastic differential systems with variable delays by using a contraction mapping principle.

Periodic dynamics of a general switching dynamical system
European Journal of Applied MathematicsSeasonal changes and cyclical human activities (such as periodic fishing bans, Wolbachia-based mosquito population control, and school term breaks) have significant impacts on population dynamics.
