Multiple mixing for a class of conservative surface flows
Bassam Fayad, Adam Kanigowski
Arnol'd and Kochergin mixing conservative flows on surfaces stand as the main and almost only natural class of mixing transformations for which higher order mixing has not been est…
Stabilisation de la formule des traces tordue VII: descente globale
Jean-Loup Waldspurger
We begin the proof of the stabilization of the twisted trace formula. Here we prove that almost all "coefficients" appearing in this formula are equal to their endoscopic counterpa…
A direct proof of Malus' theorem using the symplectic structure of the set of oriented straight lines
Charles-Michel Marle
We present a direct proof of Malus' theorem in geometrical Optics founded on the symplectic structure of the set of all oriented straight lines in an Euclidean affine space. Nous p…
Global Propagation of Singularities for Time Dependent Hamilton-Jacobi Equations
Piermarco Cannarsa, Marco Mazzola, Carlo Sinestrari
We investigate the properties of the set of singularities of semiconcave solutions of Hamilton-Jacobi equations of the form \begin{equation*} u_t(t,x)+H(\nabla u(t,x))=0, \qquad\te…
Second-order sensitivity relations and regularity of the value function for Mayer's problem in optimal control
Piermarco Cannarsa, Hélène Frankowska, Teresa Scarinci
This paper investigates the value function, , of a Mayer optimal control problem with the state equation given by a differential inclusion. First, we obtain an invariance proper…
Poincare's forgotten conferences on wireless telegraphy
Jean-Marc Ginoux, Loic Petitgirard
At the beginning of the twentieth century while Henri Poincaré (1854-1912) was already deeply involved in the developments of wireless telegraphy, he was invited, in 1908, to give…
