==Description==

[https://catalog.utsa.edu/undergraduate/sciences/mathematics/#courseinventory MAT 4233. Modern Abstract Algebra]. (3-0) 3 Credit Hours.
  
The objective of this course is to introduce the basic concepts of abstract algebra, look into the interaction of algebraic operations with foundational constructions, such as products of sets and quotient sets, and to develop rigorous skills needed for further study.
+
Prerequisites: [[MAT3233]].
The course will focus on groups and homomorphisms, as well as provide an introduction to other algebraic structures like rings and fields.  
+
Basic properties and examples of semigroups, monoids, and groups, detailed study of permutation, dihedral, and congruence groups, cyclic groups, normal subgroups, quotient groups, homomorphism, isomorphism theorems, direct products of groups, rings and fields and their basic properties, ideals, polynomial rings. Generally offered: Spring. Differential Tuition: $150.
  
==Evaluation==
 
  
* Midterms and an optional final.
