On a kinetic model for a simple market economy
Stephane Cordier, Lorenzo Pareschi, Giuseppe Toscani
In this paper, we consider a simple kinetic model of economy involving both exchanges between agents and speculative trading. We show that the kinetic model admits non trivial quas…
Truncations of multilinear Hankel operators
Aline Bonami, Sandrine Grellier, Mohammad Kacim
We extend to multilinear Hankel operators the fact that some truncations of bounded Hankel operators are bounded. We prove and use a continuity property of bilinear Hilbert transfo…
On ergodic theorems for free group actions on noncommutative spaces
Claire Anantharaman-Delaroche
We extend in a noncommutative setting the individual ergodic theorem of Nevo and Stein concerning measure preserving actions of free groups and averages on spheres of even…
Scaling Estimates for Solutions and Dynamical Lower Bounds on Wavepacket Spreading
David Damanik, Serguei Tcheremchantsev
We establish quantum dynamical lower bounds for discrete one-dimensional Schrödinger operators in situations where, in addition to power-law upper bounds on solutions corresponding…
Nash type inequalities for fractional powers of non-negative self-adjoint operators
Alexander Bendikov, Patrick Maheux
Assuming that a Nash type inequality is satisfied by a non-negative self-adjoint operator , we prove a Nash type inequality for the fractional powers of . Under some as…
Maximum boundary regularity of bounded Hua-harmonic functions on tube domains
Aline Bonami, Dariusz Buraczewski, Ewa Damek +2
In this paper we prove that bounded Hua-harmonic functions on tube domains that satisfy some boundary regularity condition are necessarily pluriharmonic. In doing so, we show that…
