Luigi Bianchi: Differential Geometry and Continuous Transformation Groups

Modern LaTeX working editions and controlling source witnesses for two works by Luigi Bianchi. Lezioni di geometria differenziale, Volume I (1902). The record contains the complete-length Italian working transcription, English working translation, exact 543-frame source scan, and one sources/QA supplement. The public files use descriptive bibliographic names. Lezioni sulla teoria dei gruppi continui finiti di trasformazioni. Anno 1902–1903 (1903). The record contains cumulative Italian and English readers through handwritten numbered page 116, the complete 731-frame TIB Hannover color photographic source (shelfmark Mr.I 583; DOI 10.14463/GBV:885209656), and one consolidated sources/QA supplement. The mathematical body of the published volume is handwritten. The former internal production label is removed from the public interface. The transformation-groups readers now restore the source equation label (3₁), which earlier readers had silently normalized to (3′). Both corrected readers were built twice in clean fixed-epoch runs with byte-identical outputs and zero recorded TeX diagnostics; all 69 pages in each language were rendered and reviewed at page scale. They remain partial source-witnessed working editions, not critical editions and not claims of complete symbol-by-symbol replay. The direct Italian-to-Simplified-Chinese translation of the differential-geometry volume is still in production and is not included in this version.
