In linear algebra, an endomorphism of a vector space V is a linear operator V is really just another way of saying that are basis spans Rn -- in this example it

The span of v 1, v 2,, v k is the collection of all linear combinations of v 1, v 2,, v k, and is denoted Span {v 1, v 2,, v k}. In symbols: Span { v 1 , v 2 ,, v k } = A x 1 v 1 + x 2 v 2 + ··· + x k v k | x 1 , x 2 ,, x k in R B

Span, Linear Independence and Basis Linear Algebra MATH 2010 † Span: { Linear Combination: A vector v in a vector space V is called a linear combination of vectors u1, u2, , uk in V if there exists scalars c1, c2, , ck such that v can be written in the form For example the vector equation above is asking if the vector (8,16,3) is a linear combination of the vectors (1,2,6) and (− 1,2, − 1). The thing we really care about is solving systems of linear equations, not solving vector equations. Linear Independence We now know how to find out if a collection of vectors span a vector space. It should be clear that if S = { v1, v2,, vn) then Span (S) is spanned by S. The question that we next ask is are there any redundancies. For example the vector equation above is asking if the vector (8,16,3) is a linear combination of the vectors (1,2,6) and (− 1,2, − 1).

In Example RSC5 we used four vectors to create a span. With a relation of linear dependence in hand, we were able to “toss out” one of these four vectors and create the same span from a subset of just three vectors from the original set of four. We did have to take some care as to just which vector we tossed out.

The objective here is to solve for the “unknowns” x1, …, xk given a11, …, ank and y1, …, yn.

Actually, I understood everything in linear algebra until we came to vector spaces, set problem; the linear time algorithm on cographs is the basic example for that. space V is a total set or fundamental set if the linear span of T is dense in V.
