DESCRIPTION:Title: Mixed identities and boundary dynamics in weakly hyperbo
 lic groups.\n\nAbstract: A group $G$ is mixed identity free (MIF) if there
  is no nontrivial word $w ∈ G * F_n$ such that every homomorphism $G * F_n
  → G$ that is the identity on $G$ sends $w$ to $1$. For groups admitting g
 eneral-type action on hyperbolic spaces\, a pure algebraic condition of be
 ing MIF is equivalent to a dynamical condition of an action on the limit s
 et in the Gromov boundary. This gives us a rigidity phenomenon for the gro
 up actions. I will discuss this result\, its corollaries\, and mention the
  applications to the transitivity degree of weakly hyperbolic groups.\n\nW
 e will gather in the lounge for teatime after the talk\, and then we will 
 go for dinner with Ekaterina.\n
