Abstract
Motivated by recent work of Masser and Zannier on simultaneous torsion on the Legendre elliptic curve Eλof equation Y2= X (X − 1)(X − λ), we prove that, given n linearly independent points P1(λ),…, Pn(λ) on Eλwith coordinates in Q(λ), there are at most finitely many complex numbers λ0 such that the points P1(λ0),…, Pn(λ0) satisfy two independent relations on Eλ0. This is a special case of conjectures about unlikely intersections on families of abelian varieties.File in questo prodotto:
