Put in a couple of links. Did you link to Wikipedia’s Pontrjagin duality because nLab’s isn’t good enough?

Did you link to Wikipedia’s Pontrjagin duality because nLab’s isn’t good enough?

We should never directly link to Wikipedia, except out of a References-section. Not because it is not good to link to Wikipedia, but because we will at some point have to go back and change the links to point to the relevant nLab-entry. But we will certainly forget to do that.

I did not just link in brackets, but explicitly said:

cf. wikipedia, Pontrjagin duality.

That means that I explicitly liked to cite Pontrjagin duality in that sentence and emphasised that I am citing them and not just linking to a default dictionary or wiki entry. I do agree that one should never just put in brackets hidden wikipedia link, every link in the $n$Lab by default is inner link and the external links should be fairly clear that they are external.

I have added redirect Fourier analysis to Fourier transform and said few words why. New entry harmonic analysis.
