Minkowski, Hecke, Landau, Sylvester, and Other Classical Mathematics Authors: Modern LaTeX Drafts

General author cluster for the Modern LaTeX Editions of Mathematics Manuscripts project. This record holds working packets for authors that are not yet split into dedicated author records, including Minkowski, Hecke, Landau, Sylvester, Steinitz, Frobenius, Bianchi, Poincare, Kneser, Kronecker, Picard, Klein-Fricke, and related classical mathematics. Status at a glance. This is a staging shelf. Some packages are source-checked working drafts; others are update packets, provenance, or repair materials. Readers should use package README/status files and the public GitHub mirror for current status and correction pathways. Latest update. Adds Poincare Tome I v1_13, extending the current Poincare differential-equations stream through Chapter IV. Bianchi A2 material has additional local loose pages under review, but incomplete continuity prevents promotion in this update. Corrections and collaboration.
