Adolf Kneser: Lehrbuch der Variationsrechnung, German Source and English Translation Working Drafts

Dedicated Kneser record for the Modern LaTeX Editions of Mathematics Manuscripts project. This record holds source-witnessed German LaTeX transcriptions, English translation working drafts, cumulative reader surfaces, source witnesses, and audit/progress material for Adolf Kneser's Lehrbuch der Variationsrechnung. Current public coverage: cumulative German-source and English working-translation reader surfaces through p0011-p0248, with a high-quality source-witness PDF through p0001-p0248. The included worklist reports 248 of 336 source pages tracked as done, or about 73.8 percent. New in this dedicated author record: fronts the German and English cumulative PDF/TeX reader surfaces, includes the p0001-p0248 high-quality source witness, and preserves the p0234 lower-p0248 current-slice/audit package. The latest slice covers sections 53-55 and completes the Sixth Section. The next continuation point is p0249, Seventh Section, section 56. Quality note: source-witnessed working drafts, not certified critical editions. The latest package reports source-visible manual checking and math-consistency checks for displayed formula chains, but it does not claim final critical closure. Source scans and audit ledgers remain the authority. Verify important formulas, theorem statements, notation, diagrams, references, and page-level continuity against the included source witnesses.
