首先,当顶点数给定时,triangle-free graph最多有几条边。这就是Mantel定理。第一种思路是发现相邻点的邻域不交,因此d(x)+d(y)有上界,加总得到边数上界。第二种思路是发现某点的邻域是独立集,于是取最大度的顶点来全局估计。 进一步地,我们会思考给定顶点数和边数时能否对三角形数给出一个下界。不涉及具体...

The Graph Theory and Algebraic Combinatorics Conference (GTACC) is a conference that is organized every year. The aim of this conference is to exchange research ideas among the algebraic combinatorics and graph theory. In addition, specialists in the subject of graph theory and combinatorics can pre...

Although the course will be largely divided into two parts (graph theory in the first half and additive combinatorics in the second), we will emphasize the interactions between the two topics and highlight the common themes.Textbook: Yufei Zhao, Graph Theory and Additive Combinatorics: Exploring ...
Combinatorics and Graph Theory packs an immense amount in, offering largely self-contained introductions to both graph theory and combinatorics along with a shorter look at infinite combinatorics. This introduces the reader to two of the more intuitive and immediate areas of mathematics and gives them...
‘Yufei Zhao’s book is a wonderful book about graph theory, additive combinatorics, and their surprising connections involving a major theme of modern mathematics: the interplay between structure and randomness. In both areas, the book can take the curious reader, whether an advanced undergraduate ...
This book covers a wide variety of topics in combinatorics and graph theory. It includes results and problems that cross subdisciplines, emphasizing relationships between different areas of mathematics. In addition, recent results appear in the text, illustrating the fact that mathematics is a living...
