I interest the software, which understands gamma and sigma matrices, that the convolution can go over Lorentz indexs, and over group indexs, which understands what is covariant differentiation, trace.(adsbygoogle = window.adsbygoogle || []).push({});

I tried to use maple, but work goes with difficulty. Although I write convolution over different indexs, maple works with such expressions with difficulty. Maybe is there another program which easy understands what I want from one? (Preferably with the tex syntax and a support forum. But I listen to any recommendations)
