WebThis theorem uses the algebraic notion of dimension: the cardinality of a linearly inde-pendent spanning set where the linear combinations use nitely many nonzero vectors at a time. This is in contrast to analysis, where linear combinations may have in nitely many nonzero terms and the dual space is the continuous linear functionals. The fact ... WebMar 6, 2024 · Definition The cardinality of a basis is called the dimension of V. Theorem Let V be a finite dimensional vector space with dimension n. Then any spanning set of V has cardinality ≥ n and any linearly independent subset of V has cardinality ≤ n. Proof. Follows from Theorem 2.
