I just saw this and I have a few comments on the interface to the Polynomial class. 1. the name FieldType is mathematically misleading since the instantiating type is very likely not to be a field (e.g. int or a multiple precision integer type). 2. the Polynomial class provides a fairly minimilist set of supported functions. This may well be deliberate (if so, apologies), but I would like to see a richer interface including such things as - content (gcd of coefficients, where that makes sense) - polynomial discriminant - resultant of 2 polynomials - evaluation of homogeneous polynomial ( f(x) = sum c_i x^i, f(a,b) = sum c_i a^i b^(d-i) ) - evaluation at a polynomial (f(g(x))) - Pseudo-division of polynomials - finding roots over C - finding roots over F_p - factorisation over Z - factorisation over F_p Chris
