Reducibility refers to the ability to simplify a problem by transforming it into a more manageable form while preserving certain properties. In the context of map coloring, reducibility is used to understand how complex maps can be represented through simpler configurations that maintain the essential characteristics needed for proper coloring, such as ensuring that no adjacent regions share the same color. This concept is fundamental in analyzing the conditions under which a specific coloring can be achieved, especially concerning the famous Four Color Theorem.
