摘要
An OU sequence is a cyclically ordered sequence in symbols O and U such that the number of O's is equal to that of U's. Every knot diagram defines an O'U sequence by reading O and U at over-and under-crossings, respectively, appeared along the diagram. In this note, we determine the OU sequences for a 2-bridge knot arising from its diagrams with two over-bridges.
