Skills: Numeracy T/F A Problem Solving T/F A Written and Spoken Communication F (in tutorials) Content: Vector subspaces, sums and intersections, complementary subspaces, quotients. Dual spaces and bases, transpose of a linear map, annihilators. Inner product spaces over R and C. CauchySchwarz inequality and applications. GramSchmidt orthonormalization. Orthogonal subspaces and complements. Duality. Linear operators on inner product spaces. Orthogonal and unitary groups; (skew) symmetric and (skew) hermitian matrices.
