For many species living in changing environments, processes during one season influence vital rates in a subsequent season in the same annual cycle. The interplay between these carry-over effects between seasons and other density-dependent events can

In this paper we investigate the presence of oscillations and simple dynamics in $x'(t)=-\nu x(t)+f(x(t))g(x(t-\tau))$. Specifically, we prove that the global attraction towards a nontrivial equili...

In this paper we study the scalar delay differential equation $$\begin{aligned} x'(t)=\alpha (t) x(t-g_{1}(t)) f(a(t),x(t-g_{2}(t)))-\beta (t) x(t) \end{aligned}$$ x ′ ( t ) = α ( t ) x ( t - g 1 ( t ) ) f ( a ( t ) , x ( t - g 2 ( t ) ) ) - β (

Let $$h:V\subset {\mathbb {R}}^{2}\longrightarrow {\mathbb {R}}^{2}$$ be an embedding. The aim of this paper is to analyze the dynamical behavior of h depending on the number of fixed points and 2-cycles, their local behaviors and the features of V.

In this paper we extend the classical “decomposing+embedding” method for systems of delay differential equations. Our extension has two advantages: (1) enhancing the range of applicability of the classical method and (2) providing delay dependent

In this paper, we analyze a class of reaction-diffusion systems with delay and a Neumann condition from the dynamical behavior of the map that determines the equilibria. For scalar equations, a sim...

A class of dissipative orientation preserving homeomorphisms of the infinite annulus, pairs of pants, or generally any infinite surface homeomorphic to a punctured sphere is considered. We prove that in some isotopy classes the local behavior of such
