課程目標 |
Algebra structures appear as common abstract structures of underlying symmetries in various areas of mathematics, and conversely the language and concepts of algebra have integrated naturally into all modern mathematics, both pure and applied, as useful tools to describe various phenomena in a systematical way. The goal of the course is to equip students the knowledges of the most basic objects (groups, rings, modules and fields) in abstract algebra. After the course, we hope that students shall feel comfortable in using language from algebra in all areas of sciences. |
