Knot invariants

Stick number

In the mathematical theory of knots, the stick number is a knot invariant that intuitively gives the smallest number of straight "sticks" stuck end to end needed to form a knot. Specifically, given any knot , the stick number of , denoted by , is the smallest number of edges of a polygonal path equivalent to . (Wikipedia).

How to use decimal points

👉 Learn all about decimals. Decimals are numbers written with a decimal point. Digits can be written to the right or to the left of the decimal point. Digits are written to the left of the decimal point increase in value by multiples of 10 while digits written to the right decrease by mul

Erik Broman: Higher dimensional stick percolation

R. Roy introduced the so-called stick percolation model in 1991. This model was a Poisson point process of sticks in R2 where the sticks had random lengths and zero widths. More recently, physicists and chemists have used higher dimensional sticks as a model for studying phenomena such as
