Given two elliptic curves, each of which is associated with a projection map that identifies opposite elements with respect to the natural group structure, we investigate how their corresponding projective images of torsion points intersect. 
Elliptic curves with large intersection of projective torsion points
We construct pairs of elliptic curves over number fields with large intersection of projective torsion points.
Torsion of elliptic curves and unlikely intersections
We study effective versions of unlikely intersections of images of torsion points of elliptic curves on the projective line.
Elliptic curves with common torsion $x$-coordinates and hyperelliptic torsion packets
We establish a connection between torsion packets on curves of genus 2 and pairs of elliptic curves realized as double covers of the projective line Px that have many common torsion x-coordinates.Expand
Division polynomials on the Hessian model of elliptic curves
In this paper we derive formulas for the scalar multiplication by n map, denoted [n], on the Hessian model of elliptic curve. This enables to characterize n-torsion points on this curve. TheExpand
On the $$\mathrm{PGL}_{2}$$-invariant quadruples of torsion points of elliptic curves
Let E be an elliptic curve and $$\pi :E\rightarrow {\mathbb {P}}^{1}$$ a standard double cover identifying $$\pm \, P\in E$$. It is known that for some torsion points $$P_{i}\in E$$, $$1\leqslantExpand
Pairs of elliptic curves with $22$ common projective torsion points
For $i=1,2$, let $E_{i}$ be an elliptic curve defined over $\overline{\mathbb{Q}}$, $E_{i}[\infty]$ the collection of all torsion points, and $\pi_{i}:E_{i}\to\mathbb{P}^{1}(\overline{\mathbb{Q}})$ aExpand

Elliptic curves with maximal Galois action on their torsion points
