How do you represent a coordinate-independent tensor? Don't you still need a basis?

[antognini → selestify]

You just call it something like T. If you want any numbers you need a coordinate basis.

For those interested, the first chapter of Kip Thorne's book has a good, though idiosyncratic, explanation of tensors: http://www.pmaweb.caltech.edu/Courses/ph136/yr2012/1201.1.K....

The first lectures here https://theoreticalminimum.com/courses/general-relativity/20... are mostly an introduction to tensor calculus.
