Odd-homology thickness conjecture for algebraic links with a positive tail

About 17 years old · traced to

Let pip_i and qjq_j be positive alternating rational tangles, with m≥2m\ge2, n≥2n\ge2, and let +k+k denote a sequence of kk pluses, where k≥1k\ge1. Consider the algebraic link (p1,…,pm+k)−(q1,…,qn)(p_1,\ldots,p_m+k)-(q_1,\ldots,q_n). Let p‾i\overline p_i and q‾j\overline q_j denote the reduced tangles and set q=min⁡(q‾1,…,q‾n)q=\min(\overline q_1,\ldots,\overline q_n).

Positive-tail thickness conjecture. The link is Kh‾′\overline{Kh}'-thick if q>1q>1 and either

min⁡(p‾1,p‾2,…,p‾m)>1,k<q,\min(\overline p_1,\overline p_2,\ldots,\overline p_m)>1,\qquad k<q,

or

min⁡(p‾1,p‾2,…,p‾m)=1,k+1<q.\min(\overline p_1,\overline p_2,\ldots,\overline p_m)=1,\qquad k+1<q.

This is the next criterion in the paper's computational analysis of algebraic links. The supplied text gives no resolution status.
