{"product_id":"9781461275732","title":"The Foundations of Topological Graph Theory","description":"\u003cp\u003eThis is a book on topological graph theory written from a purely combinatorial viewpoint. The aim is to develop a rigorous approach to the foundations of the subject. The book should therefore appeal to graduate students and researchers in topological graph theory. The basic tool used is the idea of a 3-graph which is a cubic graph endowed with a proper edge colouring in three colours. A special case of a 3-graph, called a gem, provides a model for a cellular imbedding of a graph in a surface. Thus theorems about imbeddings of graphs become theorems about gems. In the book we show that many of these theorems generalise to theorems about 3-graphs.\u003c\/p\u003e","brand":"Springer New York","offers":[{"title":"Default Title","offer_id":47015405224176,"sku":"9781461275732","price":129.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/7593\/9824\/files\/9781461275732_p0.jpg?v=1763673148","url":"https:\/\/shop-qa.barnesandnoble.com\/products\/9781461275732","provider":"Barnes \u0026 Noble (DEV)","version":"1.0","type":"link"}
