摘要
本論文旨在探究賽局理論。賽局理論是關於決策的一門學科且經常運用在經濟學上，但我在這裡只關注如何用它來寫小說。 首先，本文會介紹賽局理論的理論，這裡主要由三部分組成： 1. 如何描述一個策略遊戲。 2. 奈許均衡，它是賽局理論中關於解的概念，它就像某種穩定狀態使得沒有玩家可以藉由單方面改變他的行動來獲得更高的利益。 3. 可理性化行動與強被支配行動的反覆消除，這些也是賽局理論中關於解的概念，不過是比奈許均衡還要弱的解的概念。 第二，我會介紹《詐欺遊戲》與它的內容，它是一本由甲斐谷忍所畫的日本漫畫。 第三，我會說明如何用賽局理論來分析《詐欺遊戲》，更精確地說，就是用前三章介紹的理論來解釋作品《詐欺遊戲》的。 最後，我會說明如何利用賽局理論來寫作。

賽局理論並列摘要
This essay aims to discuss game theory.Game theory is a study of decision making and is usually used in economics, but I will focus on story writing here. Firstly, this paper will give a brief introduction to game theory, which consists of three main parts: 1. How to describe a strategic game. 2. Nash equilibrium, which is asolution concept of gametheory,and which is like some steady state such that no player can change his action to gain more utility. 3. Rationalizability and iterated elimination of dominated actions, which are also solution concepts of game theory, but which are weaker than Nash Equilibrium. Secondly, I will introduce the comic series“Liar Game” and its content. It is a Japanese comic series created by Shinohu Kaitani. Thirdly, I will show how to analyze “Liar Game” by using game theory. More precisely, the theories introduced in chapter 1, chapter 2 and chapter 3will be used to explain the logic structure of the plot of “Liar Game”. Finally, I will explain how to use game theory in story writing.
