Luigi Bianchi: Modern LaTeX Working Drafts 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 audit/repair packages for Bianchi differential-geometry and transformation-group texts. Status at a glance. Volume I of Lezioni di geometria differenziale remains represented 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, is now represented as an Italian/English working manuscript branch through source p0105. OCR/image-analysis material is witness/locator evidence only; source scans and package audit ledgers control mathematical readings. Latest update. Adds Bianchi_A2_cont_p0001_0105_IT_EN_20260612.zip, continuing the A2 branch through source p0105 and adding the required A2 notation logbook and machine-readable equation indices. The package contains Italian and English current p0091-p0105 TeX/PDF, cumulative Italian/English p0001-p0105 TeX/PDF, current and cumulative source witnesses, PNG witnesses, page/formula ledgers, notation logbook, raw cumulative display-equation index, summation-limit audit material, build logs, render checks, package manifest, metrics, and checksums. The source-page total is currently recorded as 105 of 731 pages, approximately 14.36%; the next continuation is source p0106. Quality note. These are working/source-witnessed drafts and repair packets, not certified critical editions. Readers should verify important formulas, theorem statements, matrix dots, prime marks, summation superscripts, and notation against the included source witnesses. Corrections and collaboration.
