This book is intended to provide graduate students and researchers in graph theory with an overview of the elementary methods of graph Ramsey theory. It is especially targeted towards graduate students in extremal graph theory, graph Ramsey theory, and related fields, as the included contents allow the text to be used in seminars. It is structured in thirteen chapters which are application-focused and largely independent, enabling readers to target specific topics and information to focus their study. The first chapter includes a true beginner's overview of elementary examples in graph Ramsey theory mainly using combinatorial methods. The following chapters progress through topics including the probabilistic methods, algebraic construction, regularity method, but that's not all. Many related interesting topics are also included in this book, such as the disproof for a conjecture of Borsuk on geometry, intersecting hypergraphs, Turan numbers and communication channels, etc.

In human communication, sending an unclear message is often regarded as failure or impoliteness. Nevertheless, it is not always the case that those who make explicit statements are the most successful communicators. Equivocal communication is widely employed by modern politicians, and it can also be possible to extend its scope further, to communication between nations. In this book, Bavelas et al.'s theory of equivocation is applied to analyze nine public texts (1979 - 2000) concerning the discussion of national reunification between Taiwan and Mainland China as their political communication is not normally conducted clearly and directly. A comparison will also be made between western societies and eastern societies to explore their different attitudes towards equivocation. The analysis should be especially useful to professionals in Communications and Social Psychology fields, or anyone else who may be considering utilizing ambiguity strategies for political diplomacy.
