On the structure of the divisor class group of a class of curves over finite fields
Let \(L(t)\) be the numerator of the zeta-function of the curve \(\mathcal C\) over the finite field \(\mathbb{F}_q\). We investigate the group structure of the Jacobian of \(\mathcal C\) in the case that all roots of \(L({t\over\sqrt q})\) are roots of unity.
