The spread of ideas in online social networks is a crucial phenomenon to understand nowadays the proliferation of fake news and their impact in democracies. This makes necessary to use models that mimic the circulation of rumors. The law of large num

A discussion on local bifurcations of codimension one and two is presented for generic unfoldings of Hopf-Bogdanov-Takens singularities of codimension three. Among all identified bifurcations, we focus on Hopf-Zero and Hopf-Hopf bifurcations, since,

Local bifurcation theory is used to prove the existence of chaotic dynamics in two well-known models of tritrophic food chains. To the best of our knowledge, the simplest technique to guarantee the emergence of strange attractors in a given family of

This paper is concerned with Hopf-Bogdanov-Takens singularities, that is, singularities of 4-dimensional vector fields whose 1-jet is linearly conjugate to y ∂ ∂ x − v ∂ ∂ u + u ∂ ∂ v . They first occur in generic 3-parameter families.

It is known from the literature that a family consisting of two brusselators linearly coupled by diffusion unfolds strange attractors due to the generic occurrence of a 4-dimensional nilpotent singularity of codimension 4. In this paper the attention

The main goal of this paper is to prove analytically the existence of strange attractors in a family of vector fields consisting of two Brusselators linearly coupled by diffusion. We will show that such a family contains a generic unfolding of a 4-di

In [7] we proved that a system consisting of two brusselators linearly coupled by diffusion contains strange attractors. In this paper we will give numerical examples of the chaotic behaviour predicted by the theoretical results. Some details about e

In 1977 Makanin stated that the solvability problem for word equation systems is decidable ([10]). Makanin’s algorithm is very complicated and the solvability problem for word equations remains NP-hard ([1]). We show that testing solvability of wor

One of the most intrincate algorithms related to words is Makanin’s algorithm for solving word equations. Even if Makanin’s algorithm is very complicated, the solvability problem for word equations remains NP-hard if one looks for short solutions
