# Unlikely intersections in algebraic groups and Shimura varieties

March 28 to April 1, 2011

at the

American Institute of Mathematics, Palo Alto, California

organized by

Jonathan Pila and Umberto Zannier

## Original Announcement

This workshop will explore the recent conjectures onunlikely intersections'' due to Zilber, Pink, and Bombieri-Masser-Zannier, and related or analogous problems in model theory, diophantine geometry, and arithmetic dynamics. A particular objective is to increase dialogue between some different interested communities whose interests centre on: (i) Shimura varieties/Andre-Oort conjecture, (ii) diophantine questions on multiplicative groups and abelian varieties, (iii) arithmetic dynamics, and (iv) mathematical logic.
