    Examples. The function : → given by = {⁡ (− −), ∈ (−,),is an example of a bump function in one dimension. It is clear from the construction that this function has compact support, since a function of the real line has compact support if and only if it has bounded and closed support.

Support (mathematics) - Wikipedia

    https://en.wikipedia.org/wiki/Support_(mathematics)
    In mathematics, the support of a real-valued function f is the subset of the domain containing those elements which are not mapped to zero. If the domain of f is a topological space, the support of f is instead defined as the smallest closed set containing all points not mapped to zero. This concept is used very widely in mathematical analysis

Function of compact support - Encyclopedia of Mathematics

    The support of is the closure of the set of points for which is different from zero . Thus one can also say that a function of compact support in is a function defined on such that its support is a closed bounded set located at a distance from the boundary of by a number greater than , where is sufficiently small.
