DESCRIPTION:Title: Algorithms detecting stability and Morseness for finitel
 y generated groups.\n\nAbstract: For a word-hyperbolic group G\, the notio
 n of quasiconvexity is independent of the choice of a generating set and a
  quasiconvex subgroup of G is quasi-isometrically embedded in G. Kapovich 
 provided a partial algorithm which\, on input a finite set S of G\, halts 
 if S generates a quasiconvex subgroup of G and runs forever otherwise. How
 ever\, beyond word-hyperbolic groups\, the notion of quasiconvexity is not
  as useful. For a finitely generated group\, there are two recent generali
 zations of the notion of a quasiconvex subgroup of a word-hyperbolic group
 \, a 'stable'' subgroup and a 'Morse'' subgroup. In this talk\, we will di
 scuss various detection and decidability algorithms for stability and Mors
 eness of a finitely generated subgroup of mapping class groups\, right-ang
 led Artin groups\, toral relatively hyperbolic groups.\n
