Interpreting a vector expression

  1. Feb 18, 2010 #1
    In R^3 I have two vectors a and b and the operator D = (d/dx,d/dy,d/dz)

    What is the interpretation/ picture of (aD)b - (bD)a? This is another vector.

    You mean a geometrical interpretation? It's the Lie derivative, [itex]{\mathcal L}_A B[/itex].
