Mathemical concept

In hyperbolic geometry, the Meyerhoff manifold is the arithmetic hyperbolic 3-manifold obtained by ( 5 , 1 ) {\displaystyle (5,1)} surgery on the figure-8 knot complement. It was introduced by Robert Meyerhoff (1987) as a possible candidate for the hyperbolic 3-manifold of smallest volume, but the Weeks manifold turned out to have slightly smaller volume. It has the second smallest volume

V m = 12 ( 283 ) 3 / 2 ζ k ( 2 ) ( 2 π ) 6 = 0.981368 {\displaystyle V_{m}=12\cdot (283)^{3/2}\zeta _{k}(2)(2\pi )^{-6}=0.981368\dots }

of orientable arithmetic hyperbolic 3-manifolds, where ζ k {\displaystyle \zeta _{k}} is the zeta function of the quartic field of discriminant 283 {\displaystyle -283} . Alternatively,

V m = ( L i 2 ( θ ) + ln | θ | ln ( 1 θ ) ) = 0.981368 {\displaystyle V_{m}=\Im ({\rm {{Li}_{2}(\theta )+\ln |\theta |\ln(1-\theta ))=0.981368\dots }}}

where L i n {\displaystyle {\rm {{Li}_{n}}}} is the polylogarithm and | x | {\displaystyle |x|} is the absolute value of the complex root θ {\displaystyle \theta } (with positive imaginary part) of the quartic θ 4 + θ 1 = 0 {\displaystyle \theta ^{4}+\theta -1=0} .

Ted Chinburg (1987) showed that this manifold is arithmetic.
