Syllabus Past Exams Syllabus: i) Quick review of solutions of a system of linear equations, vector spaces, sub- spaces, linear independence and span, Zorns lemma and existence of basis, quotient spaces and direct sum of vector spaces, exact sequences and splittings, linear maps and matrices, matrix of a linear map in a basis, invertibility, rank and determinant, linear functionals, dual space, annihilator, transpose of a linear map. [This part is mostly a review and should be covered quickly with emphasis on problem solving.] ii) Eigenvalues, algebraic and geometric multiplicities, characteristic and minimal polynomials, upper triangularization, diagonalizability and semisimplicity, decomposition into nilpotent and semisimple matrices, Cayley-Hamilton Theorem. iii) Tensor product of vector spaces, extension of scalars, complexification, tensor product of linear maps, symmetric and exterior algebra, determinant as a multilinear map and Laplace expansion. iv) Inner-product spaces, orthogonality, Gram-Schmidt orthogonalization, Bessels inequality, projection and orthogonal projection, symmetric and Hermitian operators, orthogonal and unitary diagonalizability, normal operators, spectral the- orem, bilinear and quadratic forms, positive definite operator, square-root of a positive operator, polar decomposition, isometry, rigid motions, the rotation group. v) Structure theory of finitely generated modules over PID and application to canonical forms.
