      One-relator groups and proper 3-realizability 

      Cárdenas Escudero, Manuel Enrique; Fernández Lasheras, Francisco Jesús; Quintero Toscano, Antonio Rafael; Repovš, Dušan (European Mathematical Society, 2009)
      How different is the universal cover of a given finite 2-complex from a 3-manifold (from the proper homotopy viewpoint)? ...
