Numerical solution[edit]

This is a great article, but I think it would be great if it gave a primer on how to solve the equation numerically. Joelthelion (talk) 20:39, 19 July 2013 (UTC)

Sorry for mixup[edit]

I thought someone had replaced many of the nabla symbols with delta symbols and changed everything to nablas removing the deltas.

Sorry, my mistake; I have just realized the use of a notation I was not familiar with. I apologize - have reverted the article to original state. (talk) 21:45, 28 March 2012 (UTC)

Excellent article[edit]

This seems to me an exceptionally clear (and concise) overview of the subject.

I don't know where the "class = B" rating comes from, but I would call this article a model of exposition.

Qualitative and technical description[edit]

This article currently lacks a qualitative and technical definition of the Laplace equation. See Spherical_harmonics#Laplace.27s_spherical_harmonics for a good technical wording for the definition. A qualitative definition remains to be provided and should be included at the very beginning of the article so that a non-expert reader can gain some understanding. --BBUCommander (talk) 20:45, 15 May 2013 (UTC)

Wrong index in Curvilinear coordinates[edit]

Correct me if I'm wrong, but I believe that the second index on the metric should be , not , inside the derivative. I.e., the equation would read

Currently there are two free indices, , in the first term and none in the second term. I believe there should be no free indices since it is a scalar equation.
