Bornes de torsion et un théorème effectif du pgcd
Hyuk Jun Kweon, Madhavan Venkatesh
We prove an effective, probabilistic version of Deligne's `théorème du pgcd' for a smooth, projective, geometrically integral (\textit{nice}) variety …

Bounds on the Torsion Subgroups of Néron-Severi Groups
Hyuk Jun Kweon
Let be a smooth projective variety defined by homogeneous polynomials of degree . We give explicit upper bounds on the order of the torsion…
