arXiv Trending Math — Weekly, 2026-09-18

This is the weekly mathematics cast for September eighteenth, twenty twenty-six. We are looking at six recent papers selected from mathematics on arXiv. The strongest visible pattern is a cluster of ambitious theorem-level claims. Chapters 00:00 Headline 01:11 The isoperimetric inequality and CMC hypersurfaces in Cartan-Hadamard manifolds 03:12 Boolean Small-Ball Inequalities for Discrepancy Theory 04:50 Universal completeness of exponentials 06:37 Regularity of asymptotically axisymmetric solutions to the 3D Navier–Stokes equations with analytic forcing 08:43 Generic Uniqueness of Isoperimetric Regions in Arbitrary Dimension 10:30 On the ACC for Minimal Log Discrepancies for Bounded Generalized Sub-Pairs 12:20 Trending Research Themes 14:01 Open Problems and Research Directions 15:13 Takeaway 16:11 Sources Papers 1.
