Web3. We are currently covering special relativity in the theoretical physics lectures where we defined: d s 2 := d t 2 − d x 2 − d y 2 − d z 2. In Road to Reality, this is introduced using a metric tensor g μ ν which is d i a g ( 1, − 1, − 1, − 1). With a scalar product between two (four-row) vectors x and y. x, y := g μ ν x μ y ν. WebThis means that the resulting operator is a scalar: for any scalar function f, f is a scalar. You might be confused because there are two meaning of "acting on" here. The metric acts on vectors (or covectors) because it is a tensor; if you give it two vectors you get a number. The D'Alembertian and the gradient ∂ are differential operators ...
