How does abstract index notation work? What do the the indices represent? I know the Lorentz transformation tensor in arbitrary direction, so if you want to use a specific tensor in an example, that would be a good one.
In Wald's book he write:
"Thus, the distinction between the index notation and the component notation is
much more one of spirit (i.e., how one thinks of the quantities appearing) than of
substance (i.e., the physical form the equations take)."
So,don't worry it much .
"Question- abstract index notation" is a way of representing mathematical equations or concepts using symbols and indices. It is often used in the field of physics and has applications in other areas of science as well.
Unlike traditional mathematical notation, which uses variables and operators, "Question- abstract index notation" uses abstract symbols and indices to represent quantities and their relationships. It is more compact and allows for easier manipulation of equations.
One of the main benefits of using "Question- abstract index notation" is its ability to represent complex equations and concepts in a concise and elegant way. It also allows for a more systematic approach to problem-solving and can reveal underlying patterns and symmetries in equations.
One potential disadvantage of "Question- abstract index notation" is that it may be less intuitive for those who are not familiar with it. It also requires a good understanding of mathematical concepts and notation in order to use it effectively.
There are many resources available for learning "Question- abstract index notation", including textbooks, online tutorials, and courses. It may also be helpful to practice using it in solving problems and equations in your field of study.
