The self-linking number obtained by moving vertically (along the blackboard framing) is known as Kauffman's self-linking number. The linking number is defined for two linked circles; given three or more circles, one can define the Milnor invariants, which are a numerical invariant generalizing linking number.
DNA supercoiling can be described numerically by changes in the linking number Lk. The linking number is the most descriptive property of supercoiled DNA. Lk o, the number of turns in the relaxed (B type) DNA plasmid/molecule, is determined by dividing the total base pairs of the molecule by the relaxed bp/turn which, depending on reference is ...
In knot theory, the self-linking number is an invariant of framed knots. It is related to the linking number of curves. A framing of a knot is a choice of a non-zero non-tangent vector at each point of the knot. More precisely, a framing is a choice of a non-zero section in the normal bundle of the knot, i.e. a (non-zero) normal vector field.
Linking bank accounts is a way to make it easier to transact between the two.
The linking number (Lk) describes the number of times that the two single-strands of DNA cross each other in a closed circular DNA molecule. Relaxed DNA molecules have an intrinsic linking number (Lk 0) corresponding to the twisting of the two single-strands around each other in the double helix, approximately once per 10.5 base-pairs (Tw 0 ...
