A vector space is a mathematical structure that consists of a set of vectors and a set of operations that can be performed on those vectors. The vectors in a vector space can be added together and multiplied by numbers, and the resulting vectors will still be part of the vector space. This allows for the representation and manipulation of a wide range of mathematical objects, such as geometric figures, physical quantities, and functions.
There are several properties that a set of vectors must satisfy in order to be considered a vector space. These include closure under vector addition and scalar multiplication, associativity and commutativity of vector addition, existence of a zero vector, existence of additive inverses, and distributivity of scalar multiplication over vector addition. These properties ensure that the operations performed on vectors in a vector space are well-defined and consistent.
A subspace is a subset of a vector space that also satisfies all the properties of a vector space. In other words, a subspace is a smaller vector space that is contained within a larger vector space. For example, a plane in three-dimensional space can be considered a subspace of the three-dimensional vector space.
To determine if a subset of a vector space is a subspace, it must be shown that the subset satisfies all the properties of a vector space. This can be done by checking if the subset is closed under vector addition and scalar multiplication, if the zero vector and additive inverses exist within the subset, and if the properties of associativity, commutativity, and distributivity hold within the subset.
The basis of a vector space is a set of linearly independent vectors that span the entire vector space. This means that every vector in the vector space can be written as a linear combination of the basis vectors. The number of basis vectors in a vector space is called the dimension of the vector space and is an important property used to classify different types of vector spaces.
