Cataclysms for Anosov representations

In this paper, we construct cataclysm deformations for $\theta$-Anosov representations into a semisimple non-compact connected real Lie group $G$ with finite center, where $\theta \subset \Delta$ is subset of the simple roots that invariant under opposition involution. These generalize Thurston's cataclysms on Teichm\"uller space and Dreyer's Borel-Anosov $\mathrm{PSL}(n, \mathbb{R})$. We express deformation also in terms boundary map. Furthermore, show are additive behave well respect to composing representation homomorphism. Finally, injective Hitchin representations, but not general representations.
