In Schaum's outline of tensor calculus, the author stipulates (page 3):
a_{ij}(x_i + y_j) \not= a_{ij}x_i + a_{ij}y_j
but I...
Hello all,
I have a quick question on Einstein notation. I'll write the tensors as a capital letter and the covariant indices as lower case letters (and not use anything that has contravariant indices). I'll also use != for not equal or not congruent to.
