Luigi Bianchi: Modern LaTeX Working Editions and Source-Intake Witnesses

Dedicated Luigi Bianchi record for the Modern LaTeX Editions of Mathematics Manuscripts project. This record contains Italian source transcription, English translation working drafts, source scan witnesses, and auditfix packages for Bianchi's differential-geometry and transformation-group texts. Status at a glance. Volume I of Lezioni di geometria differenziale remains complete as a package-audited Italian/English working edition through source pdfpages 001-543. The A2 branch, Lezioni sulla teoria dei gruppi continui finiti di trasformazioni, remains incomplete. OCR/image-analysis material is witness/locator evidence only; source scans and package audit ledgers control mathematical readings. Latest update. Adds an A2 auditfix package through source p0050, covering the canonical body through section 7. This auditfix corrects the Theta cofactor prose indexing in section 7 and the cumulative section-8 index heading from xi_si(x) to xi_si(x'). It should be preferred for the p0001-p0050 layer. The broader p0001-p0066 A2 package remains available as the wider current branch, but this p0001-p0050 auditfix is the corrected layer for the overlapping pages. Corrections and collaboration.
