The density of elliptic curves over with a rational 3-torsion point or a rational 3-isogeny
Stevan Gajović, Lazar Radičević, Matteo Verzobio
We determine the probability that a random Weierstrass equation with coefficients in the -adic integers defines an elliptic curve with a non-trivial -torsion point, or with a…

Computing structure constants for rings of finite rank from minimal free resolutions
Tom Fisher, Lazar Radičević
We show how the minimal free resolution of a set of points in general position in projective space of dimension explicitly determines structure constants for a ring of ra…

Some minimisation algorithms in arithmetic invariant theory
Tom Fisher, Lazar Radičević
We extend the work of Cremona, Fisher and Stoll on minimising genus one curves of degrees 2,3,4,5, to some of the other representations associated to genus one curves, as studied b…
