Wikipedia thorn
Feb. 21st, 2012 02:23 amSo over on MathOverflow, Philip Ehrlich confirms that Gonshor's definition is the same as Kruskal's, and that Alling's definition is also the same as this except restricted to infinitesimals. Also, when people talk about surreal exponentiation, this is the definition they're talking about.
Which leaves the question of where the definition currently appearing on Wikipedia ever came from. Tracing through the history, it seems that whole section was added by one Michael K. Edwards. So I'd ask him, but seems he's on wikibreak till November. Well, actually, seems he hasn't been seen on WP since June of 2011... oh well, I'll put it on his talk page anyway... :-/
Addendum: Seeems that wikibreak notice has been up since 2006. Guess it's pretty unlikely he'll show up again. I suppose I'll just go and remove that section later...
