👉 The term "nondegenerate" is a mathematical concept in functional analysis and topology. It refers to a set that satisfies certain properties, but does not contain any closed sets or singular points. In the context of mathematics, it can be used to describe a topological space where every point has a neighborhood that contains no isolated points (i.e., it has "nondegenerate" neighborhoods). This property ensures that the topology is well-behaved and allows for operations like compactness and separation ax
