Math 113 · Introduction to Abstract Algebra

Solutions to the Final


Syllabus for the Final

Sections:

0-6, 7 (except for Cayley digraphs), 8-11, 13-16, 18, 26-27

The format similar to both Midterms but about 50% longer as more material is to be covered.

Mastery of the concepts covered in the class is expected. Pay special attention to examples covered by Fraleigh, survey homework assignments, test your grasp of the material by answering questions ion the Theory portion of Exercises
that follow each section.

While preparing for the Final you should particularly focus on quotient structures (quotients of groups by normal subgroups, of rings by ideals), the structure of the permutations groups (both symmetric Sn and alternating An),e.g., you should be able to determine whether given two permytations are conjugate to each other or not, be able to determine the number of different conjugacy classes in Sn, be able to determine the orders of elements of Sn.

Emphasis will be also on applications of Lagrange's Theorem and of the Fundamental Theorem of the Theory of finitely Generated Abelian Groups.
