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.

Counterexamples to the L1L^1 and LL^{\infty} boundedness of the one-dimensional wave operators

This paper provides rigorous counterexamples demonstrating that the wave operators for one-dimensional Schrödinger operators with bounded, compactly supported potentials are unbounded on L1(R)L^1(\mathbb{R}) and L(R)L^{\infty}(\mathbb{R}) in generic cases and specific exceptional cases, thereby completing the characterization of their LpL^p boundedness.

Online Spectral Deflation for State Constrained Optimal Control Problems

This paper proposes an online spectral deflation strategy that accelerates the solution of parameter-dependent, state-constrained optimal control problems by reusing a single full-domain reference eigenbasis to precondition Krylov subspace solvers on varying inactive sets, achieving significant reductions in iteration counts and wall time across diverse PDE benchmarks.

Non-stationary difference equation and affine Laumon space III : Generalization to gl^N\widehat{\mathfrak{gl}}_N

This paper introduces a gl^N\widehat{\mathfrak{gl}}_N generalization of a non-stationary difference equation linked to the affine Laumon space, conjecturing that its solutions correspond to affine Laumon partition functions and verifying this connection by demonstrating that the equation reduces to the Fuji-Suzuki-Tsuda system in the four-dimensional limit.
