Cosmology has quite a few math symbols. Some are familiar using standard physics notation, others are easy to confuse or “mis-remember” such as how “T” can mean either Temperature or Frequency. Adding to that confusion, cosmology math symbols often have different meanings in other closely related fields.
So here’s a cheat sheet of common symbols used in Cosmological math. It could be helpful to Cosmology students and for those of us who have a lot of other things to remember and would like to keep our brain free for more important details. (At least that’s the excuse I’m going to use.)
If I’ve missed any vital ones, or Hubble Forbid . . . made any errors, send me a quick note and I’ll fix it as soon as I can.
