Bifurcation of limit cycles in a class of piecewise smooth generalized Abel equations with two asymmetric zones

Advanced Nonlinear Studies
This paper studies the number of limit cycles, known as the Smale-Pugh problem, for the generalized Abel equationdxdθ=A(θ)xp+B(θ)xq, $$\frac{\mathrm{d}x}{\mathrm{d}\theta }=A\left(\theta \right){x}^{p}+B\left(\theta \right){x}^{q},$$ where A and B are ...

Relaxation Oscillations in a Class of Predator-Prey Systems

, 2001
AMS Subject Classifications: Primary 34C25, 92D25; Secondary 58F14.We consider a class of three dimensional, singularly perturbed predator-prey systems having two predators competing exploitatively for the same prey in a constant environment.

On Periodic Solutions Of Systems Of Linear Functional Differential Equations

, 2007
. This paper deals with the system of functional-differential equations dx(t) dt = p(x)(t) + q(t); where p : C! (R n ) ! L! (R n ) is a linear bounded operator, q 2 L! (R n ), ! ? 0 and C! (R n ) and L!

Minimal Models of Bursting Neurons: How Multiple Currents, Conductances, and Timescales Affect Bifurcation Diagrams *

, 2004
. After reviewing the Hodgkin-Huxley ionic current formulation, we introduce a three-variable generic model of a single-compartment neuron comprising a two-dimensional fast subsystem and a very slow recovery variable.
