This workshop is part of the topical program “The Topology of Algebraic Varieties” which will take place during the 2014–2015 academic year at the Institute for Advanced Study. One theme of the workshop is to present the latest work on the possible fundamental groups of algebraic varieties. The other theme is periods of integrals, such as multiple zeta values, which are related to fundamental groups via Hodge theory, and also mixed Tate motives.
Registration for this workshop is now open at the IAS site: http://www.math.ias.edu/wfgp.
There is also an unofficial website that aims to give information about activities surrounding the Institute special year: http://www.topalg2014.org/.
