La familia paramétrica de los sistemas de FitzHugh-Nagumo es rica en bifurcaciones (Rocsoreanu et al., 2000). En este artículo estudiamos las bifurcaciones silla-nodo y de Hopf desde el punto de vista matemático de esta familia y se describen comp

Se presenta una introducción al fenómeno sorprendente de condensación de la materia a temperaturas cercanas al cero absoluto. Este fenómeno está basado en los fundamentos cuánticos de la materia. Sus principales descubridores teóricos fueron S

The improved Boussinesq equation is solved with classical finite element method using the most basic Lagrange element k = 1, which leads us to a second order nonlinear ordinary differential equations system in time; this can be solved by any standard

The nonlinear problem of traveling nerve pulses showing the unexpected process of hysteresis and catastrophe is studied. The analysis was done for the case of one-dimensional nerve pulse propagation. Of particular interest is the distinctive tendency

Several new soliton-like structures have been obtained under the consideration of non trivial boundary condition for the difference value of density in the thermodynamic model of nerve pulses. The model is based on thermodynamic principles of zero tr

We study a pure nonlinear model of a chain formed by particles that are linked each other by an enharmonic type. This lattice nonlinear Klein–Gordon model is subsequently studied in its continuum version. We use the dynamical systems approach for a

Integrate and fire processes are fundamental mechanisms causing excitable and oscillatory behavior. Van der Pol [Philos. Mag. (7) 2 (11) (1926) 978] studied oscillations caused by these processes, which he called `relaxation oscillations' and pointed

The nonlinear lattice equation of the u 6 theory is studied by using the technique of generalized coherent states associated to a SUO2U Lie group. We analyze the discrete nonlinear equation with weak interaction between sites. The existence of saddle
