Definition A vector space (V,+,.,R)isasetV with two operations + and · satisfying the following properties for all u,v 2 V and c,d 2 R: (+i) (Additive Closure) u+v 2 V. Adding two vectors gives a vector. (+ii) (Additive Commutativity) u + v = v + u.
Webalso in H: (H is closed under addition) c. Multiplying a vector in H by a scalar produces another vector in H (H is closed under scalar multiplication). Since properties a, b, and c hold, V is a subspace of R3. Jiwen He, University of Houston Math 4377/6308, Advanced Linear Algebra Spring, 2015 6 / 26
