SUMMARY

The discussion centers on the challenges faced when using Mathematica to vary the Einstein-Hilbert action. The user has successfully derived results manually but struggles with the syntax required for implementation in a notebook file (.nb). Assistance is sought to resolve these syntax issues to effectively present the findings.

PREREQUISITES
  • Familiarity with Einstein-Hilbert action in theoretical physics
  • Understanding of Mathematica syntax and notebook file structure
  • Basic knowledge of variational principles in physics
  • Experience with mathematical programming and symbolic computation
NEXT STEPS
  • Research Mathematica syntax for defining and varying actions
  • Explore examples of variational calculus implemented in Mathematica
  • Learn how to format and present mathematical results in .nb files
  • Investigate community resources or forums for Mathematica syntax troubleshooting
USEFUL FOR

This discussion is beneficial for physicists, mathematicians, and researchers using Mathematica for computational physics, particularly those working with variational principles and the Einstein-Hilbert action.

Hello ,

I was trying to vary Einstein Hilbert action in Mathematica , but the syntax failed me badly.
I have derived the result by hand , but I want to present the topic with nb.file .
Nevertheless, as I said, the syntax is my major concern now.
any help will be appreciated!
thank you

Perhaps if you present the math and the source code of your program someone here will see something.
