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.

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)[reply]

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)[reply]

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.

Punctuation, div dot

[edit]

Good faith edit was reverted because punctuation does not match rest of the article. I understand the reversion, but that leaves the original problem: the text is not clear.

 is the divergence operator,  is the gradient operator

Until you either describe the dot operator, or show that the dot is part of the "divergence operator", it's just a speck on the screen, and the paragraph is meaningless unless you already know what it means.— Preceding unsigned comment added by 121.200.27.15 (talk) 05:49, 08 November 2021 (UTC)[reply]

The divergence operator is defined in the sentence as and in the link to divergence, just as is defined the Laplace operator and in the link. I don't think there will be much confusion unless we insert a lot more punctuation and inconsistency. And since the dot is a center dot, I don't think most people will confuse it with a period.—Anita5192 (talk) 16:51, 8 November 2021 (UTC)[reply]

[edit]

why is there a 3d plot of gamma function on Laplace equation page. I can't see the relevance? Rdsk2014 (talk) 21:30, 1 December 2023 (UTC)[reply]
