I GR math

  1. May 4, 2017 #1
    Hello! I am not really sure I understand the idea of tensors and the difference between them and normal matrices, for example (for rank 2 tensors). Can someone explain this to me, or give me a good resource for this? I don't want a complete introduction to GR math, I just want to understand the idea of tensors for now. Thank you!

    Explaining tensors in general is too much for a PF thread. You might try Sean Carroll's online lecture notes on GR:


    Chapter 1 discusses tensors.

    There's also the web version of Carroll's material, starting here: https://www.preposterousuniverse.com/grnotes/
    OP may find that the "no-nonsense introduction" better meets their needs, but should be warned that some corners are being cut there.
