If already known the Action and unkown the Metric, how to get geodesic equation?

Click For Summary
SUMMARY

The discussion focuses on deriving the geodesic equation when the Action is known but the Metric is unknown. It references the paper available at http://arxiv.org/abs/1102.0529, specifically section 19.1, which outlines the methodology for this derivation. Additionally, the conversation touches on the process of deriving Riemann Curvature from the Action when the Metric is not specified. These concepts are crucial for understanding the relationship between Action and geometric properties in theoretical physics.

PREREQUISITES
  • Familiarity with the concept of Action in theoretical physics
  • Understanding of Metric tensors in differential geometry
  • Knowledge of geodesic equations and their significance
  • Basic principles of Riemann Curvature
NEXT STEPS
  • Study the derivation of geodesic equations from Action in the context of General Relativity
  • Explore Riemann Curvature and its implications in curved spacetime
  • Review advanced topics in differential geometry related to Metric tensors
  • Investigate the applications of geodesic equations in modern physics
USEFUL FOR

The discussion is beneficial for theoretical physicists, mathematicians specializing in differential geometry, and students studying General Relativity who seek to deepen their understanding of the interplay between Action and Metric in deriving geodesic equations.
