设P(K)是卫星纽结,其中模式P是Berge-Gabai纽结(即实心环面上具有非平凡实心环面Dehn运算的纽结),伴随K是S^3中的非平凡纽结。我们证明了P(K)是L空间纽结的充要条件是K是L空间纽结,且P相对于K的亏格充分正扭。数学课。结果。不是。2009(2009)2248-2274]和Hom[代数br.天啊。白杨。11(2011)219-223]。
Let P(K) be a satellite knot where the pattern P is a Berge–Gabai knot (ie a knot in the solid torus with a nontrivial solid torus Dehn surgery) and the companion K is a nontrivial knot in S^3. We prove that P(K) is an L–space knot if and only if K is an L–space knot and P is sufficiently positively twisted relative to the genus of K. This generalizes the result for cables due to Hedden [Int. Math. Res. Not. 2009 (2009) 2248–2274] and Hom [Algebr. Geom. Topol. 11 (2011) 219–223].
