Discussion Overview

The discussion revolves around the calculation of the Clebsch-Gordon coefficient for the symplectic group SP(3,R) as induced by the SU(3) group. Participants explore the theoretical implications and references related to the existence and application of SP(3,R), particularly in the context of nuclear physics.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant seeks guidance on calculating the symplectic group SP(3,R) induced by SU(3) and requests references.
  • Another participant questions the existence of SP(3,R), noting that the symplectic group typically exists only in even dimensions.
  • A different participant acknowledges the conventional understanding but cites published works that discuss SP(3,R) in nuclear physics, expressing confusion over its existence.
  • References are provided by participants, including a work that discusses the application of SP(3,R) in nuclear physics and another that describes the group itself.
  • One participant expresses a desire to engage in deeper discussion about the problem during their sabbatical year.

Areas of Agreement / Disagreement

Participants exhibit disagreement regarding the existence of SP(3,R), with some acknowledging its conventional limitations while others reference its application in specific contexts. The discussion remains unresolved.

Contextual Notes

There are limitations regarding the assumptions about the dimensionality of symplectic groups and the specific contexts in which SP(3,R) is discussed. The references provided may not fully clarify these issues.

Dear Everyone,

I have a problem to be solved now. how to calculate the symplectic group SP(3,R) non-compact induced by the SU(3) group? Any reference provided will be appreciated.

It's unclear to me what you mean by SP(3, R), since the symplectic group exists only in an even number of dimensions.
 
According to my experience, I know it exists only in an even number of dimensions. But indeed some people published some works in SP(3,R) group in nuclear physics. I am so confused. e.g.

Noncompact Lie Groups and Some of Their Applications
NATO ASI Series Volume 429, 1994, pp 285-300
Applications of Sp(3,R) in Nuclear Physics
 
Ok, I see. this reference by Bohm, Ne'eman and Barut talks a bit about the use of SP(3, R) in nuclear physics. And this reference starting on p.28 further describes the group itself.

If possible I might discuss sth with you deeply about this problem. This year is my sabbatical year so I want to solve this problem.
