Add a function for rewriting the amplitude in terms of GLIs

Open vsht opened this issue 2 years ago • 1 comments

FCLoopApplyTopologyMappings alone is not sufficient to write the given amplitude as a linear combination of GLIs (or products thereof).

Sort of fixed for scalar amplitudes, but we also need a solution for the tensor decomposition (unless one is willing to use projectors)

Fixed with 76f0e98648a2051325426f08ccae6359f5a83e36 so that now one can also do tensor reductions on the output of FCLoopFindTopologies without switching to TID/FCMultiLoopTID.

Even though I still don't think that doing multiloop tensor reductions with Mathematica is a good idea...
