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.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52125489889553,"sku":"NLS9780306110634","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":52734859477265,"sku":"NIN9780306110634","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9780306110634.jpg?v=1757465768"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-viktor-a-gorbunov.oembed","provider":"World of Books ","version":"1.0","type":"link"}
