Hi, I am using FeynCalc 9.3.1 in which version there is an implementation of a tensor called TensorFunction. I would like to ask wheter it is possible to teach Mathematica to perfom easy simplifications of TensorFunction expressions given some rules eg.: |

In particular, to perform the simplifications you mention, one would have to collect
w.r.t indices and then apply suitable replacement rules to the isolated products of tensors.
Most likely the performance will be not so good, unless you plan to look only at very
short expressions.
