• Class groups of function fields
• Cyclic extensions
• Density of class groups

In this paper we generalize a recent result of Wittmann on densities of the 4-rank of class groups of imaginary quadratic function fields to the l-rank of class groups of imaginary l-cyclic extensions of F-q(T) where is any odd prime dividing q - 1.
