Input interpretation

Cartesian tensor

Definition

A Cartesian tensor is a tensor in three-dimensional Euclidean space. Unlike general tensors, there is no distinction between covariant and contravariant indices for Cartesian tensors. However, tensors in non-Euclidean spaces (e.g., Lorentzian spaces) do require this distinction.
