#
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
on``unlikely 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.
