I have again a very specific question: I have a couple of Tensors, let's call them A[i] and B[i], that satisfy certain relations e.g. for A[i]:
I would now like to use these relations in a very long expression that includes for example
such that, the two given terms vanish.
More specifically, I face the problem that the index names are potentially different, i.e. they could occur in a form like:
Is there an easy way to obtain such a replacement rule?
All the best.
