Main Question or Discussion Point
Can anyone suggest a book from where I can learn the math used in relativity like Tensors,Minkowski spacetime metric ,etc ? A suggestion of pdfs would also be appreciated?
That depends on how you view it. I will not go into differential forms, but give the old answer. Its as sort of a generalized matrix of numbers that has certain transformation properties. It comes in two general types contravarient and covarient, and even mixed. Like matrices in linear algebra the actual numbers depend on the 'basis' of the vectors it is transforming. But the modern view is like a linear transformation in linear algebra, the actual numbers in a particular basis is not that important - the 'abstract' properties of the transformation is whats is mostly considered.Do you guys know what the basis of a tensor is?
