[GiNaC-list] question about lorentz_g contract with sy_anti tensor

[Feng Feng]

Thanks very much for your so quick reply.


Yes, my mistake,  I actually mean A^{abc}_{c} = A^{abcd} * g_{dc}


So it goes back to my original post, it seems GiNaC will not produce a 0 result.


Thanks again!


Best Regards!

Feng
