Title: Locally elliptic actions on graphical small cancellation complexes

Abstract: Graphical small cancellation extends the classical small cancellation theory and provides a powerful method for constructing nonpositively curved spaces. It is conjectured that every locally elliptic action of a finitely generated group on a finite-dimensional nonpositively curved complex is elliptic. I will show some results concerning this conjecture in the cases of graphical small cancellation complexes. This is based on joint work with Huaitao Gui.
