On totally umbilical and minimal surfaces of the Lorentzian Heisenberg groups

open access: yesMathematische Nachrichten, Volume 298, Issue 6, Page 1922-1942, June 2025.
Abstract This paper has manifold purposes. We first introduce a description of the Gauss map for submanifolds (both spacelike and timelike) of a Lorentzian ambient space and relate the conformality of the Gauss map of a surface to total umbilicity and minimality.

Mechanical Hamiltonization of Unreduced ϕ$\phi$‐Simple Chaplygin Systems

open access: yesStudies in Applied Mathematics, Volume 154, Issue 5, May 2025.
ABSTRACT In this paper, we prove that the trajectories of unreduced ϕ$\phi$‐simple Chaplygin kinetic systems are reparameterizations of horizontal geodesics with respect to a modified Riemannian metric. Furthermore, our proof is constructive and these Riemannian metrics, which are not unique, are obtained explicitly in interesting examples.

Zero‐curvature subconformal structures and dispersionless integrability in dimension five

open access: yesJournal of the London Mathematical Society, Volume 110, Issue 6, December 2024.
Abstract We extend the recent paradigm “Integrability via Geometry” from dimensions 3 and 4 to higher dimensions, relating dispersionless integrability of partial differential equations to curvature constraints of the background geometry. We observe that in higher dimensions on any solution manifold, the symbol defines a vector distribution equipped ...

Boundary Strichartz estimates and pointwise convergence for orthonormal systems

open access: yesTransactions of the London Mathematical Society, Volume 11, Issue 1, December 2024.
Abstract We consider maximal estimates associated with fermionic systems. Firstly, we establish maximal estimates with respect to the spatial variable. These estimates are certain boundary cases of the many‐body Strichartz estimates pioneered by Frank, Lewin, Lieb and Seiringer.
