SiGMa 2017

Structure in Graphs and Matroids

July 17-21, 2017

SiGMa is a workshop bringing together researchers from Graph Theory and Matroid Theory, with a focus on structure theory. The topics of the workshop include (but are not limited to) graph colourings and flows, graph and matroid connectivity, matroid representation, graph minors, matroid minors, matroid restrictions, and induced subgraphs. The meeting continues a tradition of biennial workshops organized by Bert Gerards in 2008, 2010, and 2012, and by Rudi Pendavingh and Stefan van Zwam in 2014 and 2016. This workshop will renew the emphasis on graph theory.

The workshop is held in commemoration of William T. Tutte, 1917-2002, and will take place at the University of Waterloo whose Faculty of Mathematics is celebrating its 50th anniversary.
