Discretize first, filter next: learning divergence-consistent closure models for large-eddy simulation

agdestein/incompressiblenavierstokes.jl 26 Mar 2024

We propose a new neural network based large eddy simulation framework for the incompressible Navier-Stokes equations based on the paradigm "discretize first, filter and close next".

Distributed Continuous-Time Optimization with Time-Varying Objective Functions and Inequality Constraints

star2dust/paper-simulation 4 Sep 2020

Different from most studied distributed optimization problems with time-invariant objective functions and constraints, the optimal solution in this paper is time varying and forms a trajectory.

Gromov-Wasserstein Distances between Gaussian Distributions

MaximeVandegar/Papers-in-100-Lines-of-Code 16 Apr 2021

We also study the problem without restriction on the optimal plan, and provide lower and upper bounds for the value of the Gromov-Wasserstein distance between Gaussian distributions.

Improved Exponent for Marton's Conjecture in $\mathbb{F}_2^n$

teorth/pfr 15 Apr 2024

A conjecture of Marton, widely known as the polynomial Freiman-Ruzsa conjecture, was recently proved by Gowers, Green, Manners and Tao for any bounded-torsion Abelian group $G$.
