MA8551 Algebra and Number Theory Syllabus โ€“ Anna University Regulation 2017

OBJECTIVES:

  • To introduce the basic notions of groups, rings, fields which will then be used to solve related problems.
  • To introduce and apply the concepts of rings, finite fields and polynomials.
  • To understand the basic concepts in number theory
  • To examine the key questions in the Theory of Numbers.
  • To give an integrated approach to number theory and abstract algebra, and provide a firm basis for further reading and study in the subject.
