Propagation of Coherent States through Conical Intersections
Clotilde Fermanian Kammerer, Stephanie Gamble, Lysianne Hari
In this paper, we analyze the propagation of a wave packet through a conical intersection. This question has been addressed for Gaussian wave packets in the 90s by George Hagedorn…
Global well-posedness and long-time asymptotics of a general nonlinear non-local Burgers Equation
Jin Tan, Francois Vigneron
This paper is concerned with the study of a nonlinear non-local equation that has a commutator structure. The equation reads ,…
Uncertainty principles in Gelfand-Shilov spaces and null-controllability
Jérémy Martin
We provide new uncertainty principles for functions in a general class of Gelfand-Shilov spaces. These results apply, in particular, with the classical Gelfand-Shilov spaces as wel…
Variational inequality solutions and finite stopping time for a class of shear-thinning flows
Laurent Chupin, Nicolae Cîndea, Geoffrey Lacour
The aim of this paper is to study the existence of a finite stopping time for solutions in the form of variational inequality to fluid flows following a power law (or Ostwald-DeWae…
Generation of analytic semigroup for some generalized diffusion operators in Lp-spaces
Rabah Labbas, Stéphane Maingot, Alexandre Thorel
We consider five different abstract Cauchy problems where the operator is of fourth order. For each problem, using semigroups techniques and functional calculus, we study the inver…
Microscopic derivation of a traffic flow model with a bifurcation
P Cardaliaguet, N Forcadel
The goal of the paper is a rigorous derivation of a macroscopic traffic flow model with a bifurcation or a local perturbation from a microscopic one. The microscopic model is a sim…
