Note that if G satisﬁes property P(k,q;m), then its complement is a well-covered graph with independence number q. It seems that graphs that satisfy property P(k,q;m) have not been studied WebRemark. The property P conjecture says that all nontrivial knots have property P. Modulo the Poincare conjecture, this would follow from the Gordon-Luecke theorem that knots are determined by their complements [11]. Other classes of knots for which the conjecture has been proved include satellite knots [8], and symmetric knots [3]. stents vs medication treating heart blockage

WebThe property P conjecture has been proved recently by Gordon and Luecke [ 12]. It is known that if the fundamental group of a homology 3-sphere is finite then it is either the trivial group or else the group I120 [ 18]. Therefore property I and property P together are equivalent to property PI defined as follows. Definition.

WebIn mathematics, the Property P conjecture is a statement about 3-manifolds obtained by Dehn surgery on a knot in the 3-sphere. A knot in the 3-sphere is said to have Property P if every 3-manifold obtained by performing Dehn surgery on the knot is not simply-connected. The conjecture states that all knots, except the unknot, have Property P. WebJul 23, 2010 · $\begingroup$ @David: 31858749840007945920321 is pretty large, and it took until 1988.

"WebThe proof of Theorem 1 provides a veriﬁcation of the Property P conjecture that is independent of the results of the cyclic surgery theorem of [2]. Although the argument follows [13] very closely, we shall avoid making explicit use of instanton Floer homology and Floer’s exact triangle [11, 1]. Instead, we rely on " - Property p conjecture

In 1913, Carmichael [11] proved that for every m ≠ 1, 2, 6, 12 there exists a prime p such that α (p) = m. There is an extensive literature on the order of appearance, the Fibonacci sequence in general, and related topics.
