16+ is a vector space a ring
In order to make a vector space into a ring one has to define the multiplication operatoran operator that takes two vectors and returns a vector which is. Notice that the key.
A commutative division ring.
. A vector space or a linear space is a group of objects called vectors added collectively and multiplied scaled by numbers called scalars. Locally ringed spaces have just enough structure to allow the meaningful definition of tangent spacesLet be locally ringed space with structure sheaf. Answer 1 of 9.
Equivalently a vector space is a module V over a ring F which is a field or more generally a division ring. Because a multiplication in a ring has to be times. Module and vector space First we recall some backgrounds.

In the first definition we ahve a division ring not a commutative division ring ie. We want to define the tangent space. When the scalar field is the real numbers the vector space is called a real vector spaceWhen the scalar field is the complex numbers the vector space is called a complex vector spaceThese.
Most mathematicians would call it a module over a division ring though. The basic example is n-dimensional Euclidean space Rn where every element. Usually over a field.
On Wikipedia I know I know I read that Some authors use the term. V_1v_2mapstov_1v_2 where v_1 v_2 are elements of the ring. A commutative division ring.
Answer 1 of 3. A field while in the second we have a field ie. A left module of A is an additive abelian group.
A field while in the second we have a field ie. A vector space V is a set that is closed under finite vector addition and scalar multiplication. However in a vector space multiplication is only.
Suppose A is a ring with multiplicative identity 1_A. Notice that the key difference on. In the first definition we ahve a division ring not a commutative division ring ie.
Scalars are usually considered to be real.
