unknot การใช้

• Fassel's main priority must be to unknot his offensive mess.
• If this can be done, the knot is called the unknot.
• An unknot is the identity element with respect to the knot sum operation.
• Knot theory is the recent mathematical study of unknots.
• This is the smallest possible crossing number except for the unknot and trefoil knot.
• This base case is the unknot or unlink.
• Of the twist knots, only the unknot and the figure-eight knot.
• At the other end of the spectrum, deep tissue massage unknots pent-up stress.
• It deals with the figure-eight knot and the unknot ( a simple loop ).
• Proving this requires the construction of a knot invariant that distinguishes the trefoil from the unknot.
• Actually, string figures are " unknots " or " trivial " knots.
• The special case of recognizing the unknot, called the unknotting problem, is of particular interest.
• The simplest such invariant is tricolorability : the trefoil is tricolorable, but the unknot is not.
• In three dimensions, the unknot cannot be written as the sum of two non-trivial knots.
• The crosscap number of the unknot is zero, as the Euler characteristic of the disk is one.
• It is an open problem whether any non-trivial knot has the same Jones polynomial as the unknot.
• However, there are invariants which distinguish the unknot from all other knots, such as Khovanov homology and knot Floer homology.
• In addition, virtually every major knot polynomial distinguishes the trefoil from an unknot, as do most other strong knot invariants.
• Since V is an unknotted solid torus, S ^ 3 \ setminus V is a tubular neighbourhood of an unknot J.
• Claw moved the log closer to the gate to make it easier to unknot, while Sting went to the finish line.
