Unifying interval maps and branching systems with applications to relative graph C*-algebras
Carlos Correia Ramos, Daniel Gonçalves, Nuno Martins +1
We describe Markov interval maps via branching systems and develop the theory of relative branching systems, characterizing when the associated representations of relative graph C*…
Controlling infectious diseases: the decisive phase effect on a seasonal vaccination strategy
Jorge Duarte, Cristina Januário, Nuno Martins +2
The study of epidemiological systems has generated deep interest in exploring the dynamical complexity of common infectious diseases driven by seasonally varying contact rates. Mat…
On graph algebras from interval maps
Carlos Correia Ramos, Nuno Martins, Paulo R. Pinto
We produce and study a family of representations of relative graph algebras on Hilbert spaces that arise from the orbits of points of one dimensional dynamical systems, where the u…
Activation of effector immune cells promotes tumor stochastic extinction: A homotopy analysis approach
Josep Sardanyés, Carla Rodrigues, Cristina Januário +3
In this article we provide homotopy solutions of a cancer nonlinear model describing the dynamics of tumor cells in interaction with healthy and effector immune cells. We apply a s…
Orbit Representations from Linear mod 1 Transformations
Carlos Correia Ramos, Nuno Martins, Paulo R. Pinto
We show that every point carries a representation of a -algebra that encodes the orbit structure of the linear mod 1 interval map . Such …
K-theory for Cuntz-Krieger algebras arising from real quadratic maps
Nuno Martins, Ricardo Severino, J. Sousa Ramos
We compute the -groups for the Cuntz-Krieger algebras , where is the Markov transition matrix arising from the \textit…
