DESCRIPTION:Title: <a href="https://researchseminars.org/talk/WienGAGT/3/"
 >Actions of solvable groups on hyperbolic spaces</a>\nby Sahana Balasubram
 anya (Münster) as part of Vienna Geometry and Analysis on Groups Seminar\
 n\n\nAbstract\nRecent papers of Balasubramanya and Abbott-Rasmussen have c
 lassified the hyperbolic actions of several families of classically studie
 d solvable groups. A key tool for these investigations is the machinery of
  confining subsets of Caprace-Cornulier-Monod-Tessera. This machinery appl
 ies in particular to solvable groups with virtually cyclic abelianizations
 .\n\nIn this talk\, my goal is to explain how to extend this machinery to 
 classify the hyperbolic actions of certain solvable groups with higher ran
 k abelianizations. We apply this extension to classify the hyperbolic acti
 ons of a family of groups related to Baumslag-Solitar groups.\n\nThe first
  half of the talk will cover the required preliminary information and some
  of the known results concerning the hyperbolic actions of certain solvabl
 e groups.  In the second half\, I shall explain the techniques used to pro
 ve the aforementioned results. Lastly\, I shall talk about the new results
  that we prove in our paper that generalize these techniques. \n\n (joint 
 work with A.Rasmussen and C.Abbott)\n
