Are functionals united with the vector space which they operate on?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between functionals and the vector spaces they operate on, with a focus on the conceptual and mathematical implications of this relationship. Participants explore the definitions and applications of functionals, particularly in the context of physics and behavioral psychology, and question the mathematical grounding of the terms used.

Discussion Character

  • Conceptual clarification
  • Debate/contested
  • Meta-discussion

Main Points Raised

  • Jake questions whether functionals are united with the vector spaces they operate on, using the example of physics as a functional of behavioral psychology.
  • Some participants express confusion about the relevance of the question to mathematics and vector spaces.
  • Jake seeks clarification on the term "functional" and its application to abstraction levels of concepts.
  • Jake references a Wikipedia article about spin networks and asks if the map provided by a functional is united with the spin network immersed in a manifold.
  • Participants request a mathematical definition of "united" to better understand the discussion.
  • There is a humorous response indicating that Jake's question lacks clarity and precision in mathematical terms.
  • Some participants debate whether everything can be represented mathematically, with differing opinions on the matter.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the definitions and implications of functionals and their relationship to vector spaces. There are competing views on the clarity and relevance of the original question, as well as differing opinions on the mathematical representation of concepts.

Contextual Notes

Limitations include a lack of precise definitions for terms like "functional" and "united," as well as unresolved questions about the mathematical foundations of the concepts discussed. The conversation also touches on philosophical implications, which some participants feel may detract from the mathematical focus.

Are functionals united with the vector space which they operate on? For example, Physics is a functional of Behavioral Psychology. However, Behavioral Psychology does not include Physics. Am I correct?

Thank you,

Jake
 
Physics news on Phys.org
Is this a joke?

What does this have to do with "vector spaces"? For that matter what does it have to do with mathematics?

Perhaps it would help if you gave a precise definion for your use of "functional" here.
 
I assumed (apparently incorrectly) that functionals could be applied to the abstraction levels of concepts.

Sorry about the confusion; I'm new to these concepts.

What got me asking this question is from Wikipedia: "A spin network, immersed into a manifold, can be used to define a functional on the space of connections on this manifold."
http://en.wikipedia.org/wiki/Spin_network

So I guess what I'm really asking is: Is the map the functional provides, on the space of connections on a manifold, united with the spin network that is immersed into the manifold in order to obtain the functional?

Thanks,

Jake
 
Also, could you give us a mathematical meaning to "united"?

The best I can do is try conceptually: In the concept of spacetime, space is united with time. Does that bring to mind a mathematical representation?

Thank you for bearing with me,

Jake
 
Lol, this is really funny actually. No offense, but you're not making any sense. :) . These math concepts have very precise meanings... if you want a philosophical discussion, you should ask in the philosophy forum. :)
 
But isn't everything representable with math?
 
No, why in the world would you think so?

What can't be defined with math? That's kind of a philosophy question, and I can already hear objections to this thread turning into that. So if you don't want to, don't worry about not responding.
