Answer 2

Your Solution:

In mathematics, a fence, also called a zigzag poset, is a partially ordered set in which the order relations form a path with alternating orientations. A fence may be finite, or it may be formed by an infinite alternating sequence extending in both directions.

Circulation is the amount of force that pushes along a closed boundary or path. It's the total "push" you get when going along a path, such as a circle. A vector field is usually the source of the circulation. And of course, zero circulation means zero curl.

I hope you got it.
