Why Are Subspaces Important?

An example, among many, of the usefulness of the concept of subspaces is that it is itself a vectorspace. Hence once a vectorspace has been built, one can construct many more examples by considering its vectorspace. Also, it gives us an easy way to check that a space is a vectorspace.

Why are invariant subspaces important?

The kernel of an operator, its range and the eigenspace associated to the eigenvalue of a matrix are prominent examples of invariant subspaces. ... The search for invariant subspaces is one of the most important themes in linear algebra.

What are vector subspaces used for?

Vector spaces have many applications as they occur frequently in common circumstances, namely wherever functions with values in some field are involved. They provide a framework to deal with analytical and geometrical problems, or are used in the Fourier transform.
