Click For Summary

Discussion Overview

The discussion revolves around the relationship between the infinite momentum frame and differential forms in mechanics, with a focus on specific equations and their implications. Participants seek clarification on the connections made by the original poster (OP) regarding light cone coordinates and their application in mechanics.

Discussion Character

  • Exploratory
  • Debate/contested

Main Points Raised

  • The OP presents equations involving light cone coordinates x+ and x-, suggesting a relationship between these and differential forms in mechanics.
  • Some participants express confusion regarding the OP's references and the clarity of the question posed, indicating a need for more context.
  • The OP mentions additional equations similar to L = L dt, including x = x dE and D = i dt, but does not elaborate on their significance.
  • Multiple participants request the OP to clarify their statements and provide references to support their claims.

Areas of Agreement / Disagreement

Participants generally do not agree on the clarity of the OP's question, with multiple voices expressing confusion and requesting further explanation. The discussion remains unresolved regarding the original inquiry.

Contextual Notes

There are limitations in the clarity of the OP's statements, as well as a lack of definitions and references that could help contextualize the equations presented. The discussion does not resolve the mathematical or conceptual connections suggested by the OP.

Let x+ and x- be the light cone coordinates x + t and x - t. The coordinate x- = log x+. The equations dx- = dx-/x+ and x+ = x+ dx- are like ds = dQ/T and dE = p dV.

d- = d- dx+

D- = d- + d- dx+

In mechanics we have L = T - V, where L = L dt. This is a complex differential form just like x+ = x+ dx- and d- = d- dx+.

Has anyone seen D- = d- + d- dx+?

Maybe you should give a bit more context or references to get some replies here. I personally don't really have a clue what you're asking precisely. Why e.g.
your relation between x+ and x- ?
 
I will post more later. for now, there are two extra equations of the same type as L = L dt

x = x dE

D = i dt

Again, I have no clue what you're referring to. If you want people to respond, you should be clear about what you're asking.

Seconded. Ddddx, please post provide some context to the question, general equations, and your thinking behind this. In short, explain what you're talking about in more detail please.
 
This thread is closed. The OP needs to not only explain, but also provide a reference. This seems like personal speculation.
