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, Frobenius, Poincare, Kneser, Kronecker, Picard, Klein-Fricke, and related classical mathematics. Some former mixed-shelf authors now have dedicated records; older copies here remain backstop/provenance where present. 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. Replaces Poincare Tome I v1_16 with v1_18, adds Kneser LVR p0139-p0158, and adds Frobenius 070 p016-p034 final German/English package. Poincare v1_18 is the current routed Tome I differential-equations tranche; older Poincare versions are retained only in older Zenodo versions. Kneser and Frobenius remain mixed-shelf working packets until cleaner dedicated rollups are warranted. Corrections and collaboration.
