Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".

Sous-variétés d’une variété abélienne et points de torsion. (French) Zbl 0581.14031

Let A be an abelian variety defined over the complex number field, T the torsion subgroup of A and X an integrally closed subscheme of A. Then the main theorem is: ”If TX is dense in X in the sense of Zariski topology, then X is a translation of an abelian subvariety of A with respect to a torsion point”. For a more precise statement, see theorem 3.5.1 and its corollary 3.5.2.
