Discussion Overview

The discussion revolves around the concept of group multiplication and its applicability in non-mathematical contexts. Participants explore whether certain mathematical structures, particularly involving the natural numbers, can be interpreted or represented in terms of group operations.

Discussion Character

  • Debate/contested, Technical explanation, Conceptual clarification

Main Points Raised

  • Some participants assert that ##\mathbb{N}## is not a group, questioning the initial premise of the discussion.
  • Others clarify that the product ##A \times B## does not resemble a vector product and suggest it may be a direct product instead.
  • A participant proposes the interpretation of writing ##\{3a, a \in \mathbb{N}\}## as ##\mathbb{N} \cdot 3##, indicating that while it may seem awkward, it is understandable.
  • Another participant suggests describing the output as ##\{(a,3a)\}##, providing a potential representation of the concept discussed.
  • There are multiple mentions of formatting issues with LaTeX, indicating a need for clarity in mathematical expressions.

Areas of Agreement / Disagreement

Participants generally disagree on the classification of ##\mathbb{N}## and the nature of the products discussed, with no consensus reached on the applicability of group multiplication in the context presented.

Contextual Notes

There are limitations in the discussion regarding the assumptions about group properties and the definitions of products being used, which remain unresolved.

TL;DR
Okay, what I mean:
Lets say I have the group ##\mathbb{N}##
If I have a vector product of A x B which has a, 3a
Can I write Dom(R) as ##\mathbb{N}## and Range(R) as ##\mathbb{N} * 3##?
Sorry if it didnt belong.
its not at calculus or linear algebra.

##\mathbb N## is not a group. Do you mean set?

Use double dollars or double hashes to fix your Latex.
 
This question is a mess. ##\mathbb{N}## is no group, to begin with. Then your product ##A\times B## doesn't look like a vector product. It's probably a direct product.

If you have groups, you can build semidirect, or direct products. Also, tensor products are possible in certain cases.
 
Are you asking if you can write ##\{3a, a \in \mathbb{N}\}## as ##\mathbb{N}\cdot 3##? It looks awkward but its possible to understand what you mean.

You can describe the output as ##\{(a,3a)\}##.
 
Thanks guys for the answers.
Sorry for my bad latex... ( and bad english )
