Results 1 to 10 of about 197 (51)
, 2018 We obtain a new quantitative deformation lemma, and then gain a new mountain pass theorem. More precisely, the new mountain pass theorem is independent of the functional value on the boundary of the mountain, which improves the well known results (\cite ...

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.

Global exponential stability of nonautonomous neural network models with continuous distributed delays [PDF]
, 2013 For a family of non-autonomous differential equations with distributed delays, we give sufficient conditions for the global exponential stability of an equilibrium point. This family includes most of the delayed models of neural networks of Hopfield type,

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.
