In mathematics, the support of a real-valued function

From Wikipedia, the free encyclopedia In mathematics, the support of a real-valued function is the subset of the function's domain consisting of those elements that are not mapped to zero. If the domain of is a topological space, then the support of is instead defined as the smallest closed set containing all points not mapped to zero. This concept is used widely in mathematical analysis. Suppose that is a real-valued function whose domain is an arbitrary set The set-theoretic support of written is the set of points in where is non-zero: The support of is the smallest subset of with the…
