SUMMARY

Integration over the group SU(3) is defined using the Haar Measure, which serves as the invariant volume element necessary for integration on compact Lie groups. A relevant reference for understanding this concept is the document available at Haar Measure PDF. Additionally, the discussion highlights the similarity between integrating over SU(2) and the sphere S^3, suggesting that a similar framework applies to SU(3). For a comprehensive understanding, the document at this link is recommended, particularly section 4, which covers Euler-angle parametrization and the definition of the invariant volume element.

PREREQUISITES
  • Understanding of Haar Measure in the context of Lie groups
  • Familiarity with compact Lie groups, specifically SU(2) and SU(3)
  • Knowledge of Euler-angle parametrization techniques
  • Basic concepts of integration on manifolds
NEXT STEPS
  • Study the properties of Haar Measure in detail
  • Explore the integration techniques on compact Lie groups
  • Learn about the generators of SU(3) and their significance
  • Investigate the applications of SU(3) in quantum mechanics and particle physics
USEFUL FOR

Mathematicians, physicists, and researchers interested in advanced topics in group theory, particularly those focusing on integration over Lie groups and their applications in theoretical physics.

How is integration over the group SU(3) defined?
 
Physics news on Phys.org
The keyword is: Haar Measure. See for example this http://gemma.ujf.cas.cz/~brauner/files/Haar_measure.pdf" .

Sorry for the short answer, I'm in a hurry.

I passed over a discussion which shows that integrating over SU(2) is similar to that over a sphere S^3. I want a similar discussion for integration over SU(3).
Can someone please specify a reference that gives a good explanation of SU(3) (like finding generators, etc..)?
Thanks
