A Jump-Modified Wasserstein Gradient Flow for Maximum Mean Discrepancy with Energy Kernels

Ansh Desai, Jason Liu, Srujan Roplekar +1

We study a jump-modified Wasserstein gradient flow of the squared maximum mean discrepancy generated by the energy kernels $K (z) = - ∣ z ∣^{q}$ , $0 < q < 2$ , in every dimension $d \geq 2$ as wel…

Global well-posedness and scattering for mass-critical Hartree equation

Zuyu Ma, Changxing Miao, Matthew Rosenzweig +1

In this paper, we prove that the defocusing mass-critical Hartree equation is global well-posed and scatters for any initial data $u_{0} \in L^{2}$ , and prove the analogous result in th…

Sharp mean-field estimates for diffusive log/Riesz gases in the Hilbert--Schmidt regime

Matias G. Delgadino, Rishabh Gvalani, Matthew Rosenzweig

We study fixed-temperature logarithmic and Riesz gases after subtracting the leading mean-field contribution relative to a prescribed background law. For repulsive interactions in…

Uniform logarithmic Sobolev inequalities for the 2D Coulomb gas at the diffusive temperature scale

Matthew Rosenzweig

For $N \geq 2$ and $β > 0$ , consider the canonical 2D Coulomb gas ensemble \begin{equation} \mathrm{d}\mathbb{P}_{N,β}(Z) =\mathsf{Z}_{N,β}^{-1}e^{-β|Z|^2/2} \prod_{i<j}|z_i-z_j|^{β/N}\…

Fixed-particle-number optimizers for the Lieb--Oxford inequality

Matthew Rosenzweig

Let $d \geq 1$ , $0 < s < d$ , and $N \geq 1$ . We prove that the optimal fixed-particle-number constant $Λ_{N} (s, d)$ in the Riesz Lieb--Oxford ineq…

Wasserstein gradient flows of Maximum Mean Discrepancy with energy kernels

Matthew Rosenzweig, Dejan Slepčev, Lihan Wang

We study the Wasserstein gradient flow of the squared Maximum Mean Discrepancy (MMD) generated by the nonsmooth energy kernels $K (z) = - ∣ z ∣^{q}$ , $0 < q < 2$ . In dimensions $d \geq 2$ , the co…

Wasserstein gradient flows for Coulomb discrepancies

Antonin Chodron de Courcel, Matthew Rosenzweig

We study the long-time behavior of the Wasserstein gradient flow of the squared Maximum Mean Discrepancy (MMD) between a probability measure $ρ$ and a target measure $μ$ , where the…

Commutators, mean-field, and supercritical mean-field limits for Coulomb/Riesz gases

Matthew Rosenzweig

This paper is intended as a companion to the author's talk "Commutator estimates and mean-field limits for Coulomb/Riesz gases" at the 2025 Journées équations aux dérivées partiell…

Phase transitions and linear stability for the mean-field Kuramoto-Daido model

Kyunghoo Mun, Matthew Rosenzweig

We consider the mean-field noisy Kuramoto-Daido model, which is a McKean-Vlasov equation on the circle with bimodal interaction $W (θ) = cos θ + m cos 2 θ$ for $m \geq 0$ and interaction st…

Another look at regularity in transport-commutator estimates

Elias Hess-Childs, Matthew Rosenzweig, Sylvia Serfaty

We are interested in how regular a transport velocity field must be in order to control Riesz-type commutators. Estimates for these commutators play a central role in the analysis…
