Abstract

Based on the data of 12-17-crossing knots, we establish three new conjectures about the hyperbolic volume and knot cohomology: (1) There exists a constant aR>0a \in R_{>0} such that the percentage of knots for which the following inequality holds converges to 1 as the crossing number cc \to \infty: logr(K)<aVol(K)\log r(K) < a \cdot Vol(K) for a knot KK where r(K)r(K) is the total rank of knot Floer homology (KFH) of KK and Vol(K)Vol(K) is the hyperbolic volume of KK. (2) There exist constants a,bRa,b\in R such that the percentage of knots for which the following inequality holds converges to 1 as the crossing number cc \to \infty: logdet(K)<aVol(K)+b\log \det(K) < a \cdot Vol(K) + b for a knot KK where det(K)\det(K) is the knot determinant of KK. (3) Fix a small cut-off value dd of the total rank of KFH and let f(x)f(x) be defined as the fraction of knots whose total rank of knot Floer homology is less than dd among the knots whose hyperbolic volume is less than xx. Then for sufficiently large crossing numbers, the following inequality holds: f(x)<L1+exp(k(xx0))+bf(x)<\frac{L}{1+\exp{(-k \cdot (x-x_0))}} + b where L,x0,k,bL, x_0, k, b are constants.
