Core analysis concepts were given a more systematic definition-and-proof framework.
Scientific scope
First part of the 1821 book; historical formulations, not identical to later epsilon–delta formalism or all nineteenth-century rigorization.
Evidence
The linked sources identify this contribution and its scope. WRS has not independently reconstructed the scientific claims. This record is the 1821 first part. Cauchy’s definitions are historical formulations, not word-for-word modern epsilon-delta analysis, and earlier and later rigorization remains distinct.
