the search for the self in becketts theatre: waiting for godot and endgame
this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...
15 صفحه اولMinimal Seifert manifolds for higher ribbon knots
We show that a group presented by a labelled oriented tree presentation in which the tree has diameter at most three is an HNN extension of a finitely presented group. From results of Silver, it then follows that the corresponding higher dimensional ribbon knots admit minimal Seifert manifolds. AMS Classification 57Q45; 20E06, 20F05, 57M05
متن کاملA Non-ribbon Plumbing of Fibered Ribbon Knots
A closer look at an example introduced by Livingston & Melvin and later studied by Miyazaki shows that a plumbing of two fibered ribbon knots (along their fiber surfaces) may be algebraically slice yet not ribbon. Trivially, the connected sum (i.e., 2-gonal Murasugi sum) of ribbon knots is ribbon. Non-trivially [6, 1], any Murasugi sum of fibered knots (along their fiber surfaces) is fibered. I...
متن کاملThe Slice-ribbon Conjecture for 3-stranded Pretzel Knots
We determine the (smooth) concordance order of the 3-stranded pretzel knots P (p, q, r) with p, q, r odd. We show that each one of finite order is, in fact, ribbon, thereby proving the slice-ribbon conjecture for this family of knots. As corollaries we give new proofs of results first obtained by Fintushel-Stern and Casson-Gordon.
متن کاملOn the Classification Problem for Ribbon Torus Knots
An extension of the peripheral group and its associated structures such as the meridian and longitude to knots of arbitrary dimension and genus is studied. The analogous structures are shown to provide a complete algebraic invariant for oriented spun tori, by using the Tube map of Satoh. The algebraic invariant also provides a constraint on equivalence classes of welded knots in the preimage of...
