What Is a Complex Vector?
A complex vector space is a vector space whose field of scalars is the complex numbers. A linear transformation between complex vector spaces is given by a matrix with complex entries (i.e., a complex matrix).

In respect to this, are complex numbers a vector space?

With addition and scalar multiplication, the set of complex numbers forms a vector space of dimension 2 (where the scalars are the real numbers).

Likewise, is R 2 a vector space? To show that R2 is a vector space you must show that each of those is true. For example, if U= (a, b) and V= (c, d), where a, b, c, and d are real numbers, then U+ V= (a+ c, b+ d). Since addition of real numbers is "commutative", that is the same as (c+ a, d+ b)= (c, d)+ (a, b)= V+ U so (1), above, is true.

Just so, what is a real vector space?

A real vector space is a vector space whose field of scalars is the field of reals. A linear transformation between real vector spaces is given by a matrix with real entries (i.e., a real matrix).

What is the dimension of complex numbers?

The complex numbers C are both a real and complex vector space; we have dimR(C) = 2 and dimC(C) = 1. So the dimension depends on the base field. The only vector space with dimension 0 is {0}, the vector space consisting only of its zero element.

What is the standard ordered basis for complex numbers?

Consider C2 over R. Then {(1,0), (0,1), (i,0), (0,i)} is the standard basis, and the dimension is four. Every ordered pair of complex numbers can be written as a linear combination of these four elements, (a + bi, c + di) = a(1,0) + c(0,1) + b(i,0) + d(0,i), and so we have a spanning set.

What is the dimension of C?

C as an C-vector space is one dimensional. Any field as a vector space over itself is one dimensional. It has a basis of {1}.
