Disambiguation link notification for October 17
Hi. Thank you for your recent edits. Wikipedia appreciates your help. We noticed though that when you edited Localization of a category, you added a link pointing to the disambiguation page Weak equivalence (check to confirm | fix with Dab solver). Such links are almost always unintended, since a disambiguation page is merely a list of "Did you mean..." article titles. Read the FAQ* Join us at the DPL WikiProject.

Changes to logarithm
Hi Jakob!

I was who added the "Characterization of the logarithm function". I do not agree at all with your subsequent change, because:

1) I do not concede that its relative importance is low:

a) Its fundamental property happens to characterize the logarithm even without asking for continuity (just monotonicity), which is important. If you are looking for another function like that (what people try to do from time to time), you are not going to find it. b) Exactly because of this unicity proof, entropy functions (in both Thermodynamics and Information Theory) have to be defined via the logarithm and there is no other kind of function that could be an entropy. (*) c) Dieudonné, arguably one of the best analysts of the 20th Century, chose this result as the opening one for its Logarithms and Exponentials section in his most relevant Analysis book (so to him it was surely not "mostly irrelevant" or secondary).

2) I consider that the subsection where you pasted the result, "Related concepts" under "Generalizations", is totally inappropiate: it is neither a related concept nor a generalization. The correct section for this result is "Analytical properties".

3) Even if you where right about 1) (which I think you are not), I do not consider that the proper order for information in a page is in strictly descending order of importance. Readability and complexity of information are also crucial. Hence I would not agree to paste this result after several ones on limits and integrals, because it is simpler and more elementary than them in its formulation, and because it is a property strictly related with the very definition, so in my opinion it is preferable to have the readers to reach it as close to the definition as possible, even if it a bit less "fundamental" than the following ones.

(*) This could be added to the section or anywhere in the article, and I planned to do it anytime, but I need to look for a good reference to cite and I do not have much time these days.

For the reasons above I am going to revert your change.
