Definition talk:Variation of Admissible Curve

I see the introduction of $\Gamma_0$ but I can't see what its relevance is. It's introduced without any reference to anything.

If it *is* a "convention", then this convention needs to be explained in another section, because where it is, all it does is add confusion to the mind of the reader, who wonders what it's doing there. --prime mover (talk) 16:40, 12 October 2022 (UTC)
