WebJun 28, 2024 · Contracting this tensor (in this case there is just one choice) just mean "fix i = j and sum". Thus the contraction is the ( 0, 0) -tensor (i.e, the function) a 11 + a 22 + ⋯ + a n n, in other word it is nothing but the trace of the matrix. Since the entries are smooth functions of p, so is its trace. WebIn other words, even if the components of a tensor are given by $\delta_{ab}$ in some coordinate system, they will take different values in other coordinate systems. On the …
