- I am looking for a recent and explicit reference to the following:
-
- THEOREM
- Let p_i(x_1,...,x_n), 1 <=i <= m be complex polynomials. Then either
- (1) or (2) holds:
-
- (1) There exists a non-zero polynomial T in m variables so that
- T(p_1(x_1,...,x_n),...,p_m(x_1,...,x_n)) = 0 for all (x_1,...x_n).
- (ALGEBRAIC DEPENDENCE)
-
- or
-
- (2) There exists a non-zero polynomial T in m variables so that, if
- (v_1,...,v_m) is a complex m-tuple and T(v_1,...,v_m) != 0, then there exist
- (u_1,...,u_n) so that p_i(u_1,...,u_n) = v_1
- (ALGEBRAIC INDEPENDENCE)
-
- By the way, I know that this is a theorem, as several kind algebraic geometers
- have proved for me, and I know that this is a special case of some more
- sophisticated mathematics. I am interested in a source which states the above
- as explicitly as possible. Surely this was done by one of our 19th century
- friends.
- I will e-mail a summary of responses on request.
-
- Many thanks,
- Bruce Reznick
