Syllabus: 1. Commutative rings with unity: examples, ring homomorphisms, ideals, quotients, isomorphism theorems with applications to non-trivial examples. Prime and maximal ideals, Zorns Lemma and existence of maximal ideals. Product of rings, ideals in a finite product, Chinese Remainder Theorem. Prime and maximal ideals in a quotient ring and a finite product. Field of fractions of an integral domain. Irreducible and prime elements; PID and UFD.
2. Polynomial Ring: universal property; division algorithm; roots of polynomials. Gauss Theorem (R UFD implies R[X] UFD); irreducibility criteria. Symmetric polynomials: Newtons Theorem. Power Series.
3. Noetherian rings and modules, algebras, finitely generated algebras, Hilbert Basis Theorem. Tensor product of modules: definition, basic properties and elementary computations. Time permitting, introduction to projective modules.
4. Groups: Review of normal subgroups, quotient groups and homomorhism theorems. Group actions with examples, class equations and their applications, Sylows Theorems; groups and symmetry. Direct sum and free Abelian groups. Time permitting: composition series, exact sequences, direct product and semidirect product with examples.
Note: It is desirable that Item No. 1 of Algebra I is covered before Item No. 2 of Linear Algebra begins.
