Learning features from Newton's algorithm: a way to accelerate nonlinear parametrized PDE solvers

Rémy Vallot, Florian de Vuyst, Thibault Dairay +1

The paper introduces a two‑stage method that learns features from precomputed Newton trajectories to predict a surrogate solution and then apply a cheap corrective step, providing…

Chevalley-Herbrand formulas and Z p -extensions of a p-principal imaginary quadratic field

Georges Gras

Let k be an imaginary quadratic field and let p>2 be a prime number, split in k into PP'. We assume that the p-class group of k is trivial. Let 0 be the P'-valuation of…

A functional central limit theorem for kernel gradient flow and infinitesimal gradient boosting

Clément Dombry, Jean-Jil Duchamps

Building on the large-sample analysis of infinitesimal gradient boosting (Dombry and Duchamps, 2024b), we study the fluctuations of the process around its deterministic limit and e…

Low-frequency radio telescopes sensitivity to light dark matter

Ruben Zatini, Francesca Calore, Pasquale Dario Serpico

Ground-based radio telescopes are routinely used to search for light dark matter (DM) candidates such as axion-like particles or dark photons. These instruments face however inhere…

On the -extensions of a totally -adic imaginary quadratic field -- With an appendix by Jean-François Jaulent

Georges Gras

Let and split in . We prove new properties of the -extensions , distinct from the cyclotomic one; we do not assume $K/…
