Generalization of Lines, Planes (Finite Fields)

Click For Summary
In a bare-bones vector space over a finite field, a line can be defined as the set of all F-multiples of a fixed vector. The discussion confirms that the concept of a plane can also be generalized in these vector spaces. A plane through the origin is defined as the span of two linearly independent vectors. This definition is applicable to any field, including finite fields. The generalization of lines and planes remains consistent across various types of fields.

Hi, all:

Say we have a bare-bones Vector Space v, i.e., V has only the basic vector space

layout; no inner-products, etc., over a finite field .

I think then , we can still define a line in V as the set {fvo: vo in v, f in F}, i.e.,

as the set of all F-multiples of a fixed vector vo in V .

Is there a way of generalizing the notion of a plane to these vector spaces?

Thanks in Advance.

Yes, of course. This is possible in any vector space over ANY field \mathbb{K}. A plane (through the origin) is simply defined as the span of two linear independent vectors. This definition makes sense for any field \mathbb{K}, be it the rational, reals, complexes or finite fields...
 
Thread 'How to define a vector field?'
Hello! In one book I saw that function ##V## of 3 variables ##V_x, V_y, V_z## (vector field in 3D) can be decomposed in a Taylor series without higher-order terms (partial derivative of second power and higher) at point ##(0,0,0)## such way: I think so: higher-order terms can be neglected because partial derivative of second power and higher are equal to 0. Is this true? And how to define vector field correctly for this case? (In the book I found nothing and my attempt was wrong...
