## Learning outcomes

After the course, the student shall be able to pursue abstract reasoning about algebraic structures. The student shall be trained in logical thinking and in constructions of mathematical proofs. Algebraic structures appear in many disciplines within Science and Technology. The student shall be able to recognize and use such structures in his or her forthcoming work. Concretely, this means that the student shall be able to:

• Identify and describe fundamental algebraic structures such as groups, rings and fields,
• Identify algebraic substructures such as subgroups, subrings and ideals,
• Identify and describe relations between algebraic structures, such as homomorphisms and group actions,
• Define and use bijective functions between algebraic structures, with special attention to permutations,
• Use classical results in basic group theory and ring theory, such as Lagrange's theorem or Cauchy's theorem, to describe the structure of the group or the ring,
• Explain relations using mathematical proofs and logical reasoning,
• Formulate certain practical problems by means of algebraic structures.

Groups, permutations, homomorphisms, group actions, rings, ideals, modules, fields and field extensions.
