Anosov representations form a stable and rich class of discrete subgroups of semisimple Lie groups that today is recognized as the correct higher rank generalization of rank one convex cocompact subgroups of Lie groups. In this talk, I will discuss joint work with Subhadip Dey on constructing new classes of Anosov groups arising from amalgamations and HNN extensions of Anosov representations; many of these Anosov groups provide new examples of hyperbolic groups that fail to embed as discrete subgroups of rank 1 Lie groups.
