(Arc)-connectedness of the space of Z^d actions on 1-manifolds.
We will elaborate on two recent results obtained in collaboration with Hélène Eynard-Bontemps (Inst. Fourier, Grenoble):
- The space of Z^d actions by C^{1+ac} diffeomorphisms of a compact 1-manifold is path-connected;
- The space of Z^d actions by C^2 diffeomorphisms of the interval is connected.
Here, "ac" stands for absolutely continuous. I will deeply comment on several technical problems when dealing with these properties: Mather's homomorphisms, failure of Sternberg's linearization theorem, etc. Several questions will be addressed along the two lectures.

Regular orders on groups
I will discuss some recent results regarding the language complexity of (left) orders on groups. I'll focus on examples of groups having/not having positive cones that can/cannot be described by a regular language.
