Oxford Linear Algebra - What is a Vector Space?

Explore the fundamental concept of vector spaces in this 30-minute video lecture by University of Oxford mathematician Dr. Tom Crawford. Delve into the vector space axioms, starting with definitions of addition and scalar multiplication maps. Learn about the eight essential axioms: commutativity and associativity of addition, identity element, additive inverses, distributivity of scalar multiplication, and more. Witness the application of these axioms to 3D coordinate vectors as a practical example. Discover additional vector space properties, including the uniqueness of identity elements and inverses, with a detailed proof demonstrating the uniqueness of the additive identity. Access supplementary practice exercises, workbooks, and video lectures to reinforce your understanding of vector spaces and linear algebra concepts.
