Colleagues outside Bangor/Bielefeld are welcome to participate at their own costs. The matters for lectures and discussion will include the following and their interactions (i) Global actions and groupoid atlases (ii) Homotopy limits and colimits (iii) Generalised dimension theory for categories (iv) Related topics Participants (as of December 3) Bangor Ronnie Brown Tim Porter Chris Wensley Anne Heyworth Jan Snellman (Stockholm and Bangor) Emma Moore Bielefeld Tony Bak Arun Munkur Rooz Hazrat Niko Inassaridze (Tbilisi, Bangor) . Background Bak's theory of Global Actions gives a framework for an algebraic approach to higher Algebraic K-theory, and in fact has more general applications. This framework has been generalised in joint work with Bangor to the notion of Groupoid Atlas. There have emerged from previous workshops links between single domain global actions and recent work in Geometric Group Theory, including complexes of groups, higher generation by subgroups, and identities among relations for presentations.
