Definition

nabla operator

opérateur nabla

Notes

$\nabla = e_{x} \frac{\partial}{\partial x} + e_{y} \frac{\partial}{\partial y} + e_{z} \frac{\partial}{\partial z} = \sum_{i} e_{i} \frac{\partial}{\partial x_{i}}$

The operator is also called "del operator".

$\nabla = e_{x} \frac{\partial}{\partial x} + e_{y} \frac{\partial}{\partial y} + e_{z} \frac{\partial}{\partial z} = \sum_{i} e_{i} \frac{\partial}{\partial x_{i}}$

L'opérateur est aussi appelé «del operator» en anglais.
