Nonuniqueness of implicit lattice Nagumo equation [PDF]
, 2019 summary:We consider the implicit discretization of Nagumo equation on finite lattices and show that its variational formulation corresponds in various parameter settings to convex, mountain-pass or saddle-point geometries.

Existence and global attractivity of positive almost periodic solutions for a kind of fishing model with pure-delay [PDF]
, 2017 summary:By using some analytical techniques, modified inequalities and Mawhin's continuation theorem of coincidence degree theory, some sufficient conditions for the existence of at least one positive almost periodic solution of a kind of fishing model ...

Sistemas dinâmicos e equações diferenciais ordinárias
, 2013 O objetivo deste trabalho é apresentar a teoria de sistemas dinâmicos em espaços topológicos uniformes. Como uma aplicação, mostraremos a construção de um fluxo para equações diferenciais ordinárias não autônomas e, utilizando a teoria de dinâmica ...

Nonautonomous Dynamical Systems I: Topological Pressures and Entropies
Let $\boldsymbol{X}=\{X_{k}\}_{k=0}^{\infty}$ be a sequence of compact metric spaces $X_{k}$ and $\boldsymbol{T}=\{T_{k}\}_{k=0}^{\infty}$ a sequence of continuous mappings $T_{k}:X_{k} \to X_{k+1}$. The pair $(\boldsymbol{X},\boldsymbol{T})$ is called a nonautonomous dynamical system.

Topological modes of variability of the wind-driven ocean circulation
International audienceTemplexes are topological objects that encode the branching organization of a flow in phase space. We build on these objects to introduce the concept of topological modes of variability (TMVs).

The characterisation of chaos in low dimensional spaces [PDF]
This work attempts to characterise some of the complicated behaviour that is observed in many non-linear systems. For example, the frontispiece was generated by iterations of a two dimensional area-preserving mapping (the Chirikov map) that is typical
