Tree-indexed series, theory and examples II

Thursday 31st January 2013 - 15:00 to 16:00
INI Seminar Room 1
To any operad, one can associate a pro-unipotent group much alike the group of formal power series in one variable. This provides a theoretical framework for the use of tree-indexed series in numerical analysis (under the name of Butcher series) by using the PreLie operad. Some examples of tree-indexed series will be presented, with relations to polytopes and Lie idempotents.
