Course No.:S070100XJ001
Course Category:basic course of subject
Period/Credits:40/2
Prerequisites:Advianced mathematics, linear algebra, general topology, abstract algebra in college (group theory).
Aims & Requirements:
The course is the basic disciplinary course for all students for the master and PhD degree. It is necessary for the students who want to learn algebraic number theory, algebraic geometry, algebraic topology, computer science and coding theory. The main objects are the students whose majors are not algebra, also the students whose major are algebra can choose it. Through the course students can get the basic training and general knowledge in algebra. The content contains group theory, field theory, Galois theory, ring theory, module theory and so on.
