Periods modulo $p$ of integer sequences associated with division polynomials of genus $2$ curves

Yasuhiro Ishitsuka, Tetsushi Ito, Tatsuya Ohshita +2

We study an integer sequence associated with Cantor's division polynomials of a genus 2 curve having an integral point. We show that the reduction modulo $p$ of such a sequence is…

On the proportions of soluble forms in some families of locally soluble binary quartic forms

Yasuhiro Ishitsuka, Yoshinori Kanamura

An integral binary quartic form is said to be locally soluble (resp. soluble) if the corresponding genus one curve has a rational point over $Q_{v}$ for every place $v$ of $…
