Introduction à la théorie des grandes matrices aléatoires

RÉSUMÉ. Cet article est une introduction à la théorie des grandes matrices aléatoires, à destination d’un public non spécialiste. On y énonce et démontre en détail le théorème de MarčenkoPastur qui décrit le spectre asymptotique d’une grande matrice de covariance. On introduit la transformée de Stieltjes et les techniques de calcul associées, ainsi que quelques techniques de calcul gaussien qui...

3 Lorenz integrable system moves à la Poinsot

A transformation is derived which takes the Lorenz integrable system into the well-known Euler equations of a torque-free rigid body about a fixed point, i.e. the famous motionà la Poinsot. The proof is based on Lie group analysis applied to two third-order ordinary differential equations admitting the same two-dimensional Lie symmetry algebra. Lie's classification of two-dimensional symmetry a...

Médecine à la Molière.

Of Moliere's thirty six plays, seven deal, to a greater or lesser extent, with medicine; the medicine as practiced in Paris during the reign of Louis XIV. In these days, Moliere satirises the recalcitrant conservatism of the Paris medical faculty. It is, however, an informed satirisation. This paper explores Moliere's motives and attempts to place Moliere's medical plays against a broad canvas ...

Death à la carte

Delegates arrived at the hotel on a rainy Sunday evening where they were immediately made welcome and encouraged to relax over dinner while chatting to other EWCD (European Workshop on Cell Death) participants. The EWCD is a bi-annual conference that focuses on all aspects of cell death. Each conference is held in a different unique location, with this year’s being no exception. The six-day mee...
