👉 Zones in mathematics, particularly in the context of real analysis and topology, are regions within a domain (usually an open subset of Euclidean space) that are defined by a specific property or inequality. These zones can be thought of as "layers" or "regions" where certain functions or behaviors are consistent. For example, in the study of real-valued functions, a zone might be defined as the set of points where a function is continuous, differentiable, or satisfies other specific conditions. Each zone can be further subdivided into sub-zones based on more fine-grained criteria, such as the behavior of the function within those sub-zones. This hierarchical structure helps mathematicians analyze and understand complex functions by breaking them down into manageable, well-defined parts.
