143. Jonathan Kirby
Exponential algebraicity in exponential fields

Submission date: 14 November 2008.


I give an algebraic proof that the exponential algebraic closure operator in an exponential field is always a pregeometry, and show that its dimension function satisfies a weak Schanuel property. A corollary is that there are at most countably many essential counterexamples to Schanuel's conjecture.
