Schanuel's Conjecture

Let lambda_1, ..., lambda_n in C be linearly independent over the rationals Q, then

Q(lambda_1,...,lambda_n,e^(lambda_1),...,e^(lambda_n))

has transcendence degree at least n over Q. Schanuel's conjecture implies the Lindemann-Weierstrass theorem and Gelfond's theorem. If the conjecture is true, then it follows that e and pi are algebraically independent. Macintyre (1991) proved that the truth of Schanuel's conjecture also guarantees that there are no unexpected exponential-algebraic relations on the integers Z (Marker 1996).

At present, a proof of Schanuel's conjecture seems out of reach (Chow 1999).
