The well-posedness and convergence of higher-order Hartree equations in critical Sobolev spaces on
Ryan L. Acosta Babb, Andrew Rout
In this article, we consider Hartree equations generalised to order nonlinearities. These equations arise in the study of the mean-field limits of Bose gases with -body i…

A partial converse to the Riemann--Lebesgue lemma for Bessel--Fourier series of order zero
Ryan L. Acosta Babb
It is known that the Bessel--Fourier coefficients of a function such that is integrable over satisfy . We show a partial convers…

continuity of eigenprojections for 2-d Dirichlet Laplacians under perturbations of the domain
Ryan L. Acosta Babb, James C. Robinson
We generalise results by Lamberti and Lanza de Cristoforis (2005) concerning the continuity of projections onto eigenspaces of self-adjoint differential operators with compact inve…
