Let XX be a separable infinite dimensional (real or complex) Banach space. Augé in 2012 constructed a bounded operator on XX such that the set AT:={xX: Tnx}A_T:=\{x\in X:~ \|T^nx\|\to \infty\} is not dense and has nonempty interior. Moreover, he introduced the notion of wild operators. In this talk we study the class of wild operators and we introduce the notion of asymptotically separated sets, which allows us to construct operators with non-intuitive dynamics. Specifically, operators for which the set ATA_T and the set of recurrent points form a partition of the space.
