Function Fields by García and Quoos

In [1], García and Quoos consider global function fields over Fb given by the Kummer extension of the type

ym = $\displaystyle {\frac{{f(x)}}{{R(f(x))}}}$,

where m is a divisor of b−1, f is a polynomial over Fb with deg fb, and R(f (x)) denotes the reduced polynomial, obtained from f (x) by operating on its monomials as follows: R(xi) = xi for i = 0,…, b−1 and R(xi) = R(xi−(b−1)) for ib.

Based on this definition, formulas for g(F/Fb) and N(F/Fb) are obtained.

The major part of the paper consists of examples, giving explicit polynomials f and integers m yielding fields with good parameters.
