DESCRIPTION:Title: <a href="https://researchseminars.org/talk/GaTO/58/">Fo
 lding-like techniques for CAT(0) cube complexes</a>\nby Rylee Lyman (Rutge
 rs) as part of Geometry and topology online\n\n\nAbstract\nIn a seminal pa
 per\, Stallings introduced folding of morphisms of graphs. One consequence
  of folding is the representation of finitely generated subgroups of a fin
 ite-rank free group as immersions of finite graphs. Stallings's methods al
 low one to construct this representation algorithmically\, giving effectiv
 e\, algorithmic answers and proofs to classical questions about subgroups 
 of free groups. Recently Dani–Levcovitz used Stallings-like methods to s
 tudy subgroups of right-angled Coxeter groups\, which act geometrically on
  \\(\\mathrm{CAT}(0)\\) cube complexes. We extend their techniques to fund
 amental groups of non-positively curved cube complexes.\n
