We provide an accurate upper bound of the maximum number of limit cycles that this class of systems can have bifurcating from the periodic orbits of the linear center ˙ x = y, y ˙ =

, 6, then L(7) 6= 0; the origin is a fine focus of maximum order seven, at most seven small amplitude limit cycles can be bifurcated from the origin.. Sufficient

Keywords and phrases: super-Brownian motion, interacting branching particle system, collision local time, competing species, measure-valued diffusion.. AMS Subject

Using the results of Sec- tions 2, 3, we establish conditions of exponential stability of the zero solution to (1.1) and obtain estimates characterizing exponential decay of

We study in Section 3 the generalized Cauchy problem of the Dunkl linear symmetric systems, and we prove the principle of finite speed of propagation of these systems.. In the

The advection-diffusion equation approximation to the dispersion in the pipe has generated a considera- bly more ill-posed inverse problem than the corre- sponding

A variety of methods have been introduced for the synchronization of chaotic systems which include complete synchronization, generalized synchronization, phase synchronization,

Our objective in Section 4 is to extend, several results on curvature of a contractive tuple by Popescu [19, 20], for completely contractive, covari- ant representations of
