## Multiply Connected Region

in mathematics, a region in which there exist closed curves that cannot be contracted to a point within the region. In Figure 1, the region A is a simply connected region and the region B is a multiply connected region. A curve that cannot be contracted to a point within B is shown by the broken line.
