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. Adds Kneser_LVR_hqfig_p0158_0177_DE_EN_20260611.zip, a high-quality figure and scan-witness correction package for the Kneser Lehrbuch der Variationsrechnung p0158-p0177 tranche. It does not continue past p0177: the text/math scope remains the already-routed §37-§39 slice, beginning at the lower part of p0158 and stopping before §40 on p0177. The correction regenerates the current and cumulative source-scan branches from kneser_lvr_1900_archiveorg.pdf, removes visible TikZ/AI-drawn figure reconstructions, and replaces figures 1-18 in the German and English TeX/PDF outputs with source-derived whitened original crops. The package includes German/English current-slice and cumulative TeX/PDF, high-quality current and cumulative scan witnesses, figure-crop assets, figure/source/math/removal ledgers, build checks, a slop audit, and SHA256 checksums. Preferred Kneser use. Prefer this high-quality figure package over the earlier Kneser_LVR_p0158_0177_DE_EN_20260611.zip when checking figures or source witnesses through p0177. Older packages remain useful provenance and tranche history. Also current in this version. The same surface retains Frobenius_all_GE_EN_cum_scans_20260611.zip, poincare_v1_19.zip, and prior routed Frobenius/Kneser/Poincare support packets. Older versions retain superseded provenance.
