{"product_id":"9786139074051","title":"Separoid","description":"Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, a separoid is a binary relation between disjoint sets which is stable as an ideal in the canonical order induced by inclusion. Many mathematical objects which appear to be quite different, find a common generalisation in the framework of separoids; e.g., graphs, configurations of convex sets, oriented matroids, and polytopes. Any countable category is an induced subcategory of separoids when they are endowed with homomorphisms (viz., mappings that preserve the so-called minimal Radon partitions).","brand":"Part Press","offers":[{"title":"Default Title","offer_id":47064197988592,"sku":"9786139074051","price":35.64,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9786139074051_p0.jpg?v=1763720259","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9786139074051","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
