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-witnessed working drafts; others are update packets, provenance, OCR/source-witness aids, or repair materials. Readers should use package README/status files and the public GitHub mirror for current status and correction pathways.

Latest update. Adds Kneser_LVR_p0206_0219_DE_EN_20260612.zip, continuing Kneser Lehrbuch der Variationsrechnung from source p0206 lower through p0219 upper. The tranche covers §46, §47, and §48, includes Fig. 24 as a source-derived crop, visually checks formula groups (10)-(25) and (1)-(8), and reserves the lower p0219 §49 beginning for the next tranche. The package includes German/English slice and cumulative TeX/PDF, current/cumulative scan witnesses, figure/math/source ledgers, render checks, and removal/slop audit files.

Quality note. These are working/source-witnessed drafts and repair packets, not certified critical editions. Readers should verify important formulas, diagrams, theorem statements, and notation against the included source witnesses.
