Can you provide the context of this notation?

[tex]\nabla^2_{r'} V(r-r')[/tex]

where the subscript is to remind us that, as CPL.Luke says, that we are differentiating with respect to the dashed variables (or undashed, as it is in your example)

Ooops.. I meant to put the subscript on the operator not on the function. Sorry about that.

[tex]\nabla^2_{xy}=\frac{\partial^2}{\partial x^2}+\frac{\partial^2}{\partial y^2}[/tex]

This is what i would say. i believe the theta and phi in the subscript in the original post imply spherical coordinates.
