By using the averaging theory of the first and second orders, we show that under any small cubic homogeneous perturbation, at most two limit cycles bifurcate from the period annulus

In this case, the extension from a local solution u to a solution in an arbitrary interval [0, T ] is carried out by keeping control of the norm ku(T )k sN with the use of

Operation is subject to the ing two conditions: (1) This device may not cause harmful interference, ) this device must accept any interference received, including interference ay

On the other hand, from physical arguments, it is expected that asymptotically in time the concentration approach certain values of the minimizers of the function f appearing in

Theorem 4.8 shows that the addition of the nonlocal term to local diffusion pro- duces similar early pattern results when compared to the pure local case considered in [33].. Lemma

Here we continue this line of research and study a quasistatic frictionless contact problem for an electro-viscoelastic material, in the framework of the MTCM, when the foundation

In Appendix B, each refined inertia possible for a pattern of order 8 (excluding reversals) is expressed as a sum of two refined inertias, where the first is allowed by A and the
