Axioms (Vector Space)
Updated: October 26, 2020
To qualify as a vector space, a set V and its associated operations of addition (+) and multiplication/scaling (⋅) must adhere to the below:
Associativity #
u+(v+w)=(u+v)+w
Commutivity #
u+v=v+u
Identity of Addition #
There exists and element 0∈V, called the zero vector, such that v+0=v for all v∈V.
Inverse of Addition #
For every v∈V, there exists an element −v∈V, such that v+(−v)=0.
Compatibility #
a(bv)=(ab)v
Scalar/Multiplication Identify #
1v=v
where 1 denotes the scalar identity
Distributivity #
a(u+v)=au+av
