WitrynaA closed totally geodesic surface in the figure eight knot complement remains incompressible in all but finitely many Dehn fillings. In this paper, we show that there is no universal upper bound on the number of such fillings, independent of the surface. This answers a question of Ying-Qing Wu. WitrynaSome potential applications of the boundary map to the study of boundary slopes of immersed essential surfaces are discussed. In this paper, we will compute the dimension of the space of spun and ordinary normal surfaces in an ideal triangulation of the interior of a compact 3-manifold with incompressible tori or Klein bottle …

WitrynaCiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): We show that a compact hyperbolizable acylindrical 3-manifold with non-empty incompressible boundary, in which every boundary component has genus at least two, necessarily contains a closed immersed essential surface. 1 Witrynasurface. 1. Introduction An immersed surface in a 3-manifold is called essential if it is ˇ1-injective, @-ˇ1-injective and not freely homotopic into the boundary of the 3-manifold. It is known that boundary curves of embedded essential surfaces in a 3-manifold are quite restricted [3, 4]. In contrast, it is naturally conjectured that more closed smallville actor died
