Support (mathematics) - Wikipedia

    https://en.wikipedia.org/wiki/Compact_support
    The notion of closed support is usually applied to continuous functions, but the definition makes sense for arbitrary real or complex-valued functions on a topological space, and some authors do not require that f : X → R (or C) be continuous. Compact support

Continuous functions on a compact Hausdorff space - Wikipedia

    https://en.wikipedia.org/wiki/Continuous_functions_on_a_compact_Hausdorff_space
    In mathematical analysis, and especially functional analysis, a fundamental role is played by the space of continuous functions on a compact Hausdorff space with values in the real or complex numbers. This space, denoted by C(X), is a vector space with respect to

    We show, in particular, that for continuous frames, the pointfree rings of continuous functions with compact support are Noetherian if and only if the underlying set of the frame is finite; see ...

compact support in nLab

    A function f: X → V f\colon X \to V on a topological space with values in a vector space V V (or really any pointed set with the basepoint called 0 0) has compact support (or is compactly supported) if the closure of its support, the set of points where it is non-zero, is a compact subset.
