Course content

MAT2200 gives an introduction to group and ring theory with emphasis on finite groups, polynomial rings, and field extensions.

Learning outcome

After completing the course you:

  • know the fundamental definitions and results in group theory, including the Lagrange Theorem, group homomorphisms, the relation between normal subgroups and quotient groups, and the isomorphism theorems;
  • will have detailed knowledge of the structure of finitely generated abelian groups and permutation groups, and you will have learned about cyclic, dihedral, symmetric, and alternating groups;
  • have learned about group actions, orbits and stabilizer groups, and the symmetry groups of certain geometric figures;
  • know the fundamental concepts and results in ring theory, including the concepts of an ideal, quotient ring, integral domain, and field, and you will have seen examples of finite rings and fields;
  • will have learned about principal ideal domains and in more detail about polynomial rings in one variable, and you will know the fundamental properties of finite field extensions;
  • will know the proofs and applications of central theorems in one or more of the subjects:
    • Elementary number theory;
    • Burnside’s Theorem;
    • The Sylow Theorems;
    • Galois theory;
    • Classical results on constructibility.


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.


Formal prerequisite knowledge

In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:

  • Mathematics R1 (or Mathematics S1 and S2) + R2

And in addition one of these:

  • Physics (1+2)
