{"product_id":"algebraic-theory-of-quasivarieties-von-viktor-a-gorbunov","title":"Algebraic Theory of Quasivarieties","description":"The theory of quasivarieties constitutes an independent  direction in algebra and mathematical logic and specializes in a  fragment of first-order logic-the so-called universal Horn  logic. This treatise uniformly presents the principal directions of  the theory from an effective algebraic approach developed by the  author himself. A revolutionary exposition, this influential text  contains a number of results never before published in book form,  featuring in-depth commentary for applications of quasivarieties to  graphs, convex geometries, and formal languages. Key features include  coverage of the Birkhoff-Mal'tsev problem on the structure of lattices  of quasivarieties, helpful exercises, and an extensive list of  references.\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9780306110634\"\u003e\u003ch3\u003e\u003c\/h3\u003e\u003c\/div\u003e","brand":"Libri","offers":[{"title":"Hardcover - 9780306110634","offer_id":51485287942,"sku":"9780306110634","price":160.49,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/6c6ecf4c-cb53-49aa-84e5-c207a3760234.jpg?v=1772255718","url":"https:\/\/shop.autorenwelt.de\/en\/products\/algebraic-theory-of-quasivarieties-von-viktor-a-gorbunov","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
