Mathematical physics sits at the fascinating intersection where abstract equations meet the fundamental laws of our universe. This field uses rigorous mathematical tools to model everything from the behavior of subatomic particles to the curvature of spacetime, turning complex theories into testable predictions. It is the language through which physicists describe reality, bridging the gap between pure mathematics and physical observation.

On Gist.Science, we process every new preprint published in this category on arXiv to make these dense studies accessible to everyone. Whether you are a specialist or a curious reader, you will find both plain-language overviews and detailed technical summaries for each paper. Below are the latest mathematical physics papers from arXiv, curated to help you explore the cutting edge of theoretical science.

McMg: A Learned Phase-Space Multi-channel Multigrid Preconditioner for Helmholtz Equation

This paper introduces McMg, a learned phase-space multigrid preconditioner that encodes local wave information (amplitude, phase, direction, and scattering) into coarse-grid channels to efficiently solve high-frequency, heterogeneous Helmholtz equations with superior convergence and generalization compared to classical and existing neural baselines.

Poisson bracket and L∞L_\infty algebras

This paper establishes a connection between the Poisson bracket of Lagrangian field theory and L∞L_\infty algebras by demonstrating that a proposed symplectic structure yields the Peierls formula, interpreting the inverse relation between these structures via homological algebra, and applying these concepts to the complexities of pp-adic string theory.
