An algebraic function field F/k (in one variable) over a field kis a field extension F of k such that F is a finite field
extension of k(x) for an element
which is transcendental
over k.
In V2.7, the original KANT module for function fields has been
completely revised and its facilities have been vastly expanded
by Florian Hess. In particular, types have been introduced for
places and divisors. For simplicity, the complete feature set
is outlined below.
