Syllabus for the Comprehensive Exam in Algebra

  1. Vector Spaces (Linear Algebra): Matrices; vector spaces and bases; linear transformations; eigenvalues and eigenvectors; inner products and norms; orthogonality and orthogonal projections; bilinear and quadratic forms; the spectral theorem for symmetric matrices
  2. Groups: Basic facts about groups, including cyclic, dihedral, symmetric, and linear (matrix) groups; homomorphisms; cosets and quotients; normal subgroups; mapping properties and isomorphism theorems; group actions; applications of group actions to geometric and combinatorial symmetry (e.g. symmetries of regular polyhedra, Polya enumeration, and Burnside's formula); the class equation; the Sylow theorems; simple groups and composition series; the structure theorem for finitely generated abelian groups
  3. Rings: (By a ring we mean a commutative ring with identity.) Definitions; homomorphisms; ideals; quotients; mapping properties and isomorphism theorems; polynomial rings; integral domains; fraction fields; prime and maximal ideals; Euclidean domains; unique factorization domains; principal ideal domains; Gauss's lemma; irreducibility criteria; the Chinese remainder theorem
