We study the billiard dynamics in annular tables between two excentric circles. As the center and the radius of the inner circle change, a two parameters map is defined by the first return of trajectories to the obstacle. We obtain an increasing fami

In this paper we show that, under certain generic conditions, billiards on ovals have only a finite number of periodic orbits, for each period, all non-degenerate and at least one of them is hyperbolic. Moreover, the invariant curves of two hyperboli

Pheochromocytoma in cats is a rare clinical condition characterised by the development of a secretory endocrine tumour that arises from the adrenal medulla. An 8-year-old castrated male, domestic shorthair cat was referred for further investigation o

In this paper we study the topological properties of integral curves of a system of implicit differential equations associated to rarefaction curves of a system of three conservation laws. This system of equations becomes singular at the points of ei

In this paper we show that, under certain generic conditions, billiards on ovals have only a finite number of periodic orbits, for each period N, all nondegenerate. Moreover, the stable and unstable manifolds of hyperbolic points are transversal. We

We show that a C1 torus that is homologous to the zero section, invariant by the geodesic flow of a symmetric Finsler metric in T2, and possesses closed orbits is a graph of the canonical projection. This result, together with the result obtained by

We study C 1 invariant, two-dimensional tori of constant energy without singularities of the Euler–Lagrange flow of a convex, superlinear Lagrangian defined in the tangent space of a closed surface. We show that in regular energy levels, such tori

In this paper we show the existence of a plateau for the minimal action function associated with a model for a particle under the influence of a magnetic field (Hall effect). We describe the structure of the Mather sets, that is, sets that are suppor
