determinant tensor

determinant tensor

[də′tər·mə·nənt ′ten·sər]
(mathematics)
A tensor whose components are each equal to the corresponding component of the Levi-Civita tensor density times the square root of the determinant of the metric tensor, and whose contravariant components are each equal to the corresponding component of the Levi-Civita density divided by the square root of the metric tensor. Also known as permutation tensor.
