On the ergodic theory of impulsive semiflows
S. M. Afonso, E. Bonotto, J. Siqueira
We consider impulsive semiflows and establish sufficient conditions to the existence of invariant measures. Namely, the impulsive set and its image are both submanifolds of codimen…
Epidemic analysis of COVID-19 in Brazil by a generalized SEIR model
Suzete Afonso, Juarez Azevedo, Mariana Pinheiro
We shall apply a generalized SEIR model to study the outbreak of COVID-19 in Brazil. In particular, we would like to explain the projections of the increase in the level of infecti…
Equilibrium states for non-uniformly hyperbolic systems: statistical properties and analyticity
Suzete M. Afonso, Jaqueline Siqueira, Vanessa Ramos
We consider a wide family of non-uniformly expanding maps and hyperbolic Hölder continuous potentials. We prove that the unique equilibrium state associated to each element of this…
Existence, uniqueness, and approximation for solutions of a functional-integral equation in spaces
Suzete M. Afonso, Juarez S. Azevedo, Mariana P. G. da Silva +1
In this work we consider the general functional-integral equation: \begin{equation*} y(t) = f\left(t, \int_{a}^{b} k(t,s)g(s,y(s))ds\right), \qquad t\in [a,b], \end{equation*} and…
Existence of periodic solution for a class of neutral differential equations with impulses
Suzete M. Afonso, André L. Furtado
By applying a Mawhin's continuation theorem of coincidence degree theory, we establish sufficient conditions for the existence of a periodic solution for a class of impulsive neutr…
