Anosov Groups: constructions, restrictions, and ergodic aspects:  The study of discrete subgroups of Lie groups provides fertile ground for interactions between diverse areas of mathematics. This talk will specifically focus on a special type of discrete groups called Anosov groups. These groups offer a rich mixture of topological, geometric, and dynamical features, opening up intriguing pathways to navigate through the exciting landscape of discrete groups.

How expansive is the realm of Anosov groups? After a brief introduction, we will discuss recent results focusing on ways to construct new examples of these groups, look into intricate group-theoretic constraints governing them, and explore some ergodic aspects, including topics such as Hausdorff measures on their limit sets.
