摘要

The Slope Conjecture proposed by Garoufalidis asserts that the degree of the colored Jones polynomial determines a boundary slope, and its refinement, the Strong Slope Conjecture proposed by Kalfagianni and Tran asserts that the linear term in the degree determines the topology of an essential surface that satisfies the Slope Conjecture. Under certain hypotheses, we show that Mazur doubles of knots satisfy the Strong Slope Conjecture if the original knot does. Consequently, any knot obtained by a finite sequence of cabling, untwisted \(\omega \) –generalized Whitehead doublings with \(\omega > 0\) , connected sums and Mazur doublings of B–adequate knots or torus knots satisfies the Strong Slope Conjecture. On the other hand, it may be worth mentioning that under these hypotheses, if there exists a knot with a Jones slope less than \(-\frac{1}{4}\) , then its Mazur double would either provide a counterexample to the Strong Slope Conjecture or have a Jones surface that is unrelated to any Jones surface of the knot. Following work of Kalfagianni and Lee, we also use our results to show that the Mazur double of an adequate knot K with trivial writhe has crossing number either \(9c(K)+2\) or \(9c(K)+3\) .
