SUMMARY

Cartan forms and structure equations are essential for defining differentiation on geometrical objects, particularly fibre bundles. These concepts are crucial in constructing models for general relativity (GR) and string theory. For a comprehensive understanding, resources such as "Cartan for Beginners: Differential Geometry Via Moving Frames and Exterior Differential Systems" by Tom Ivey are recommended. The complexity of these topics often necessitates extensive study, as they are foundational in advanced physics and mathematics.

PREREQUISITES
  • Understanding of fibre bundles in differential geometry
  • Familiarity with general relativity (GR) concepts
  • Basic knowledge of gauge theory
  • Mathematical background in differential geometry
NEXT STEPS
  • Study the role of Cartan forms in fibre bundles
  • Explore the applications of structure equations in general relativity
  • Read "Cartan for Beginners: Differential Geometry Via Moving Frames and Exterior Differential Systems" by Tom Ivey
  • Investigate gauge theory and its connection to Cartan forms
USEFUL FOR

This discussion is beneficial for mathematicians, physicists, and students specializing in differential geometry, general relativity, and theoretical physics, particularly those interested in the mathematical foundations of advanced physical theories.

Could someone explain these two concepts? What I need is the big picture of 'why' we need this, roughly 'what' these equations mean, 'where' its used etc
Thanks in advance

omg.. nobody answering...
there aren't many people who understand these stuff eh?:rolleyes:

i think it is more of a matter of complexity. there are entire books written to answer that question.

I'll give the why, you can explore the what on your own: Cartan forms and connections allow us to define differentiation on certain geometrical objects, namely fibre bundles. This topic has proven valuable in constructing models for phenomena in GR and string theory.

Any book on gauge theory and physics will discuss this. for a heavy duty mathematical treatment, look for the book Cartan for Beginners: Differential Geometry Via Moving Frames and Exterior Differential Systems by my friend Tom Ivey.
