# What's relation between factorial and tensor components.?

1. Jun 14, 2012

maybe its simple permutation and combination technique... I ve tried to resolve it on my own but I couldn't...The textbook which I read simply mentions it to be obvious..can anyone please elucidate me the logic behind factorials of "independent components of tensor curl" and levi cita

Can anyone also explain the relation between pseudo-tensor and tensor density.?(with practical example hopefully)

It's just an artifact of using summation conventions. Levi-Civita in N dimensions generally has $1/N!$ appear somewhere.
