Observational Insights on DBI K-essence Models Using Machine Learning and Bayesian Analysis

Samit Ganguly, Arijit Panda, Eduardo Guendelman +3

We perform a late-time cosmological study; we compare the performance of two Dirac-Born-Infeld (DBI)-type k-essence scalar field extensions of the $Λ$ CDM model to the standard fram…

Extragradient with player sampling for faster Nash equilibrium finding

Carles Domingo Enrich, Samy Jelassi, Carles Domingo-Enrich +3

Data-driven modeling increasingly requires to find a Nash equilibrium in multi-player games, e.g. when training GANs. In this paper, we analyse a new extra-gradient method for Nash…

A branched transport limit of the Ginzburg-Landau functional

Sergio Conti, Michael Goldman, Felix Otto +1

We study the Ginzburg-Landau model of type-I superconductors in the regime of small external magnetic fields. We show that, in an appropriate asymptotic regime, flux patterns are d…

On the high frequency limit of the LLL equation

Pierre Germain, Laurent Thomann

We derive heuristically an integro-differential equation, as well as a shell model, governing the dynamics of the Lowest Landau Level equation in a high frequency regime.

On the continuous resonant equation for NLS: I. Deterministic analysis

Pierre Germain, Zaher Hani, Laurent Thomann

We study the continuous resonant (CR) equation which was derived by Faou-Germain-Hani as the large-box limit of the cubic nonlinear Schrödinger equation in the small nonlinearity (…

On the inviscid limit of the 2D Euler equations with vorticity along the $(L M O^{α})_{α}$ scale

Frederic Bernicot, Tarek M. Elgindi, Sahbi Keraani

In a recent paper [5], the global well-posedness of the two-dimensional Euler equation with vorticity in \mbox{ $L^{1} \cap L B M O$ } was proved, where $L B M O$ is a Banach space which is…

A Kernel Multiple Change-point Algorithm via Model Selection

Sylvain Arlot, Alain Celisse, Zaid Harchaoui

We tackle the change-point problem with data belonging to a general set. We build a penalty for choosing the number of change-points in the kernel-based method of Harchaoui and Cap…

The speed of a biased random walk on a percolation cluster at high density

Alexander Fribergh

We study the speed of a biased random walk on a percolation cluster on $Z^{d}$ in function of the percolation parameter $p$ . We obtain a first order expansion of the speed at $p = 1$ …

Biased random walks on a Galton-Watson tree with leaves

Gérard Ben Arous, Alexander Fribergh, Nina Gantert +1

We consider a biased random walk $X_{n}$ on a Galton-Watson tree with leaves in the sub-ballistic regime. We prove that there exists an explicit constant $γ = γ (β) \in (0, 1)$ , dependi…
