SUMMARY

The operator ε_{ijk}∇_k, represented as an antisymmetric gradient matrix, is used to compute the curl in three-dimensional space. This matrix is defined as follows: \begin{pmatrix} 0 & \frac{\partial}{\partial z} & -\frac{\partial}{\partial y}\\ -\frac{\partial}{\partial z} & 0 & \frac{\partial}{\partial x}\\ \frac{\partial}{\partial y} & -\frac{\partial}{\partial x} & 0 \end{pmatrix}. While the discussion inquires about a more compact symbolic representation, no simpler form has been identified beyond ε_{ijk}∇_k. This operator also serves as an analogue for the curl in higher dimensions.

PREREQUISITES
  • Understanding of tensor notation and indices
  • Familiarity with vector calculus, specifically curl operations
  • Knowledge of differential operators in three-dimensional space

Does this operator (in 3D):

[tex]ε_{ijk}∇_k = \begin{pmatrix}<br /> 0 & \frac{\partial}{\partial z} & -\frac{\partial}{\partial y}\\<br /> -\frac{\partial}{\partial z} & 0 & \frac{\partial}{\partial x}\\<br /> \frac{\partial}{\partial y} & -\frac{\partial}{\partial x} & 0<br /> \end{pmatrix}[/tex]

have a formal name and a more compact symbolic representation?

That gives you the curl in 3-D.

It gives you an analogue of the curl in other dimensions. I don't know how much more compact than ##\epsilon_{ijk}\nabla_k## you wanted, but I am not aware of any more compact forms.
