| Abstract: | 此篇論文我們主要是探討熱帶幾何下，凸集(convex set)以及圓錐(cone)的生成元素(generator)個數。在第二章中我們對一些基本環境及運算工具做介紹，例如：熱帶半環(tropical semiring)為度量空間(metric space)、極限值的運算性質等等，在第三章中我們探討回收錐(recession cone)、凸集及圓錐的性質，其中包含三者之間的關係，而在第四章中我們探討閉圓錐(closed cone)、緊緻凸集(compact convex set)、閉凸集(closed convex set)三者的生成元素個數，並以實例說明此性質，最後我們將推論出一個方法來找出在二維的熱帶空間底下的有限生成圓錐之生成元素。
In this thesis, I will discuss the generators of cone and convex set in tropical geometry. In Chapter 2, basic environment in tropical geometry and arithmetic tools are introduced here, such as how to find the limit value in tropical geometry or deciding if tropical semiring is a metric space, etc. In Chapter 3, I explore the properties of cone, convex and recession cone, inclusive of the relations of one another. In Chapter 4, the generators of a closed cone, a compact convex set, a closed convex set are provided with illustrations to present the properties. It will finally lead to a method to find the generators of the finitely generated cone in two dimesion space. |
