w_{n} is primitive root of unity of order n, w_{m} is primitive root of unity of order m,
all primitve roots of unity of order n are roots of Cyclotomic polynomials
phi_{n}(x) which is a minimal polynomial of all primitive roots of unity of order n ,
similarly, phi_{m}(y) is a minimal polynomial of all primitive roots of unity of order m ,
then, what is the minimal polynomial of (W_{n},w_{m}), if exists or no?
Thank you very much! what book I can find some subject about primitve roots of unity.
