Knots and Coloring
Presented by
Dr. Brandy Doleshal
Sam Houston State University
Dr. Doleshal explained how to make a knot into a mathematical object, and then talked about ways of distinguishing knots, using coloring
and modular arithmetic. For example, a knot is called three-colorable, if the strands of the knot can be colored using exactly three colors
so that at each crossing, either all three strands are different colors or all are the same color. See if you can decide which of the knots in
the handout below are three-colorable.
