What is the difference between vector space and linear space?
2021年8月27日 · I honestly think trying to encode the topology into the terminology "linear space" is weird. I've always seen "vector space" and "linear space" used synonymously, and I think these are appropriately named sense since "vector space" suggests we're talking about a set of vectors (and vectors are to be added and scalar-multiplied), and "linear space" suggests a set with …
What is the difference between a Set, a Vector, and, a Vector Space?
A vector space is a set in which you can add its elements with one another and in which you can "stretch" its elements, in other words multiply them by a real number. The elements of the vector space are the vectors. Some people would say vector spaces are sets with "more structure".
linear algebra - How to find the basis for a vector space ...
Find a basis for Vector space of polynomials. 0. how to find if two elements can span a vector space.
What "is" a matrix in the context of a vector space?
The action of matrices on a vector space via matrix multiplication is in some sense the same as the action of linear maps on that vector space. The equivalence depends on choosing bases. $\endgroup$ – James Staff
Why is the set of cosines and sines a vector space? - Physics Forums
2015年8月18日 · Cosines and sines are a vector space because they satisfy all of the properties required for a set to be considered a vector space. They are closed under addition and scalar multiplication, they have an identity element (1 for cosines and 0 for sines), and they have inverses (cosine and sine functions).
linear algebra - Real life applications of general vector spaces ...
2016年2月10日 · Even if they haven't taken differential equations courses before, showing that functions form a vector space is quite trivial. Once you have this, you know you can introduce the idea of a basis for this space, which lets you reliably decompose certain functions as being made up from other ones. Applications obviously abound.

What is the main difference between a vector space and a field?
The space of all meromorphic functions over a Riemann surface is a field and a vector space over $\mathbb{C}$. The space of rational function over a field $\mathbb{K}$, noted as $\mathbb{K}(x)$ form a field.
what is the relationship between vector spaces and rings?
2013年11月12日 · A vector space is a a quadruple $(V,\mathbb{F}, +, .)$ consisting of an abelian group $(V, +)$ and field $\mathbb{F}$ acting on it by scalar multiplication $.: \mathbb{F}\times V \to V.$ This scalar multiplication operation is compatible with vector addition and field addition. A ring is a triple $(R, +,\times),$ where $(R, +)$ is an abelian group.
