Question

prove that kronecker delta is mixed tenaor of rank 2​

Answer 1

I also want to know the answer

Answer 2

Answer:

Explanation:

We have Kronecker delta

δ

i

j =

∂x¯i

∂x¯j

∂xl

∂xm

δ

m

l

=

∂x¯i

∂xm

∂xl

∂x¯j

δ

m

l

therefore it has one contravariant coefficient and a covariant coefficient.

So Kronecker delta is a mixed tensor of rank two.
