We prove that a generic lagrangian has finitely many minimizing measures for every cohomology class. Annals of Maths, 167 No3. (2008).
We prove a perturbation lemma for the derivative of geodesic flows in high dimension. This implies that a C generic riemannian metric has a non-trivial hyperbolic basic set in its geodesic flow.
We prove that for a uniformly convex Lagrangian system L on a compact manifold M , almost all energy levels contain a periodic orbit. We also prove that below Mañé’s critical value of the lift of the… (More)
Three cases of Staphylococcus lugdunensis endocarditis have been reported in patients with a history of vasectomy preceding the development of endocarditis. We describe a new case of a 39-year-old… (More)
We present a counter example to a theorem given by Amir et al. J. Math. Phys. 35, 3005 (1994). We also comment on a misleading statement of the same reference. In a recent paper, M. Jamil Amir et al.… (More)
We consider a piecewise analytic expanding map f : [0, 1] → [0, 1] of degree d which preserves orientation, and an analytic positive potential g : [0, 1] → R. We address the analysis of the following… (More)
The expression of the vector field generator of a Ricci Collineation for diagonal, spherically symmetric and non-degenerate Ricci tensors is obtained. The resulting expressions show that the time and… (More)
A mini-Wright based peak flow meter (VMX Mini-Log), which stores the readings together with the time and date of each measurement, has recently been marketed but has not yet been evaluated. The… (More)
