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 Frob071_crit_GE_EN_scans_20260611.zip, a German/English Frobenius item 071 package for Theorie der hyperkomplexen Groessen II. The packet includes editable German and English TeX/PDF, source scans, formula/display inventories, alignment audit, and build/render logs. Its internal audit reports 32 German and English numbered formula tags, 61 display blocks in each branch, no diagrams or tables in the source, and no intentional prose compression. This update does not convert the mixed shelf into a final critical edition; it promotes this package as a source-scan-backed working draft. Corrections and collaboration.
