    Course Description

    Math 312 is an introduction to modern abstract algebraic systems and their applications. The course will focus on a rigorous treatment of the basic theory of groups (subgroups, quotient groups, homomorphisms, isomorphisms, group actions) and their applications.

    Prerequisites

    C or better in Math 211 and Math 163.

    Textbook

    The textbook we will use for this course Contemporary Abstract Algebra by Joseph Gallian. I will use the Ninth Edition, which is available at the University Bookstore or online

    Other editions will be very similar, but the exercises will occasionally differ. If you have a different edition, find a friend with the ninth edition to make sure the exercises you work match your friend's.

    Attendance

    Regular attendance is expected. Important dates can be found here.

  • Final Exam Schedule
  • Technology

    I first learned Abstract Algebra about 15 years ago and I would have loved to have some of the computer generated graphics and computing power available today. Check out the Group Explorer for starters.

    On the Take-Home Midterms and Exams, you are NOT allowed to use the internet.

    Outcomes and Assesment

    Upon successful completion of this course students will be able to:

  • Select and correctly apply standard proof writing techniques.
  • Describe various properties of groups, such as its subgroups, its order and isomorphisms.
  • Apply group theory to analyze symmetry and motion of common objects.
  • Evaluation of these learning outcomes will be done through a mix of assignments, class exercises, projects, research papers, group work, written & oral quizzes and tests.

    Course Description

    This course will cover most of Parts 1 and 2 text. We will study groups, subgroups and various classes such as cyclic and permutation groups. We will construct homomorphisms and isomorphisms of groups and use these to classify finite abelian groups.

  • Preliminaries and Intro to Groups - 3 weeks
  • Subgroups - 1 week
  • Cyclic Subgroups - 1 week
  • Permuatation Groups - 1 week
  • Isomorphisms - 1 week
  • Cosets and Lagrange's Theorem - 2 weeks
  • Products, Normal Subgroups and Factor Groups - 2 weeks
  • Homomorphisms - 1 week
  • The Fundamental Theorem of Finite Abelian Groups - 1 week
  • Academic Honesty: Cheating is not only unethical and pathetic, but is a violation of the Northern Michigan University Student Code and University Policy and grounds for your dismissal from the University.
