Introduction to Rings and Proofs, Begins with common features of integers, rational numbers, and polynomials, leading to a study of rings in general. Topics include divisibility, factorization, and modular arithmetic for integers and polynomials, and homomorphisms and ideals for rings. Proof techniques include direct proof, proof by contrapositive, mathematical induction, and proof by contradiction. Prerequisites: MATH 2800 and grade C or better in MATH 2250 or concurrent registration in MATH 2250. 9/4/2019 - 12/13/2019, Lecture
