The present invention assigns, in order to form a word representation for a flow pattern in a multiply connected exterior domain having N holes topologically, any one of words that define two types of flow patterns that can be topologically applied to a simply connected exterior domain having a hole, and repeatedly assigns, to the assigned word, any one of words that define five types of operations that can be topologically applied to add a hole to the flow pattern, so that a word representation corresponding to the multiply connected exterior domain having N holes is formed. |
