Sharp Estimates for Blowing Down Functions in a Denjoy-Carleman Class
André Belotto da Silva, Edward Bierstone, Avner Kiro
If F is an infinitely differentiable function whose composition with a blowing-up belongs to a Denjoy-Carleman class C_M (determined by a log convex sequence M=(M_k)), then F, in g…
Studies of heavy-ion collisions using PYTHIA Angantyr and UrQMD
André Vieira da Silva, Willian Matioli Serenone, David Dobrigkeit Chinellato +2
In this paper, we show predictions from a new QGP-free, no-equilibration, improved baseline model for heavy-ion collisions. It is comprised of the PYTHIA Angantyr event generator c…
Studying the effect of the hadronic phase in nuclear collisions with PYTHIA and UrQMD
André Vieira da Silva, Christian Bierlich, David Dobrigkeit Chinellato +1
In this work, we couple Pb-Pb events simulated with the PYTHIA Angantyr event generator at and ~TeV with the hadronic cascade simulator UrQMD to stu…
Strong Sard Conjecture and regularity of singular minimizing geodesics for analytic sub-Riemannian structures in dimension 3
A Belotto da Silva, A Figalli, A Parusiński +1
In this paper we prove the strong Sard conjecture for sub-Riemannian structures on 3-dimensional analytic manifolds. More precisely, given a totally nonholonomic analytic distribut…
A general system of differential equations to model first order adaptive algorithms
André Belotto da Silva, Maxime Gazeau
First order optimization algorithms play a major role in large scale machine learning. A new class of methods, called adaptive algorithms, were recently introduced to adjust iterat…
