Theory of motives, homotopy theory of varieties, and dessins d'enfants
April 23 to April 26, 2004
at the
American Institute of Mathematics,
San Jose, California
organized by
Gunnar Carlsson and Rick Jardine
Original Announcement
This workshop will bring together topologists working
in the developing area of "homotopy theory of varieties" with number
theorists and algebraic geometers working in subjects related to
Dessins d'enfants, and to expose them to the techniques and ideas of
the various subjects involved both in the number theoretic and
topological areas.
The major component of the meeting will be expository lectures on the different areas, at a level which could be appreciated by mathematicians outside the specialized area. There will also be extensive time allotted for discussions. A particular goal for these discussions will be to develop problems and to suggest research directions in these areas, especially directions which investigate possible interplay between the topological and arithmetic points of view.
