We state and formally prove several Farkas-like theorems over linearly ordered fields in Lean 4. Furthermore, we extend duality theory to the case when some coefficients are allowed to take ``infinite values''.", "revisions": [ { "version": "v1", "updated": "2024-09-12T15:09:07.000Z" } ], "analyses": { "keywords": [ "linear optimization", "extensions", "extend duality theory", "linear combination", "infinite values" ], "tags": [ "github project" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
