<General Relativity

If and are tensors of rank and , then there exists a tensor of rank . The components of the new tensor (pronounced "T tensor S") are obtained by multiplying the components of the old tensors. In other words, if and then .

For example, if T and S are two contravariant, one-rank tensors, then their tensor product is a two-rank, contravariant tensor.
