MA 385 - Modern Algebra with Applications3 lecture hours 0 lab hours 3 credits
Course Description
This course is an introduction to abstract algebra with a focus on elementary group theory and some of its applications. Topics include: modular arithmetic, groups, subgroups, isomorphism, external direct products, rings, integral domains and fields. Applications include: error checking/correction and the RSA encryption algorithm. (prereq: MA 235 or equivalent, junior standing)
Course Learning Outcomes
Upon successful completion of this course, the student will be able to:
• Perform modular arithmetic operations including powers and inverses of large numbers
• Identify whether or not a set together with a binary operation is a group
• relate divisibility facts to properties of cyclic groups
• Identify isomorphic groups
• Perform arithmetic operations with external direct products of cyclic groups
