Calculation of $3$-torsion ideal for some class of hyperelliptic curves
E. S. Malygina Immanuel Kant Baltic Federal University, Kaliningrad
Abstract:
In the paper, we consider hyperelliptic curves of genus two defined by the Dickson polynomials. For such curves, we calculate the $3$-torsion ideal, namely we obtain the four generators of this ideal by using the Mumford–Cantor representation for the $3$-torsion divisor and by using of $\theta$- and $\wp$-functions.
Keywords:
hyperelliptic curve, Dickson polynomial, $l$-torsion ideal, $l$-torsion divisor, modular equation.
