Course Objectives

Aims
This lecture course aims to introduce students to the basic algebraic structures such as groups, rings and fields.
Brief Decommention of the Course
This course studies abstract algebraic structures. It attempts to understand the process of mathematical abstraction, the formulation of algebraic axiom systems, and the development of an abstract theory from these axiom systems. This course will cover the topics groups, rings, fields, Euclidean domains, principal ideal domains, unique factorization domains, and field extensions. Contemporary mathematics makes extensive use of abstract algebra. Subject areas such as algebraic number theory, algebraic topology and algebraic geometry apply algebraic methods to other areas of mathematics.
Learning Outcomes
On successful completion of this course, students will be able to
a) know what is a group, subgroup, factor group, normal and centre subgroups;
b) find number of all possible abelian groups up to isomorphism for a given order;
c) know what is a pgroup and a sylow psubgroup;
d) show whether a group is simple or not;
e) know what is a ring, subring and ideal;
f) know polynomial ring, reducible and irreducible polynomials over certain rings;
g) know integral domains, Euclidean domains, principal ideal domains, unique factorization domains;
h) construct a bigger ring from a given ring;
i) know what is field and construct fields from domains;
j) know field extensions, algebraic extensions, splitting fields, algebraic closures, separable and inseparable extensions.
