locally integrable function


Definition Suppose that U is an open set in n, and f:U is a Lebesgue measurable function. If the Lebesgue integralMathworldPlanetmath

K|f|𝑑x

is finite for all compact subsets K in U, then f is locally integrable. The set of all such functions is denoted by Lloc1(U).

Example

  1. 1.

    L1(U)Lloc1(U), where L1(U) is the set of (globally) integrable functions.

  2. 2.

    Continuous functionsMathworldPlanetmathPlanetmath are locally integrable.

  3. 3.

    The function f(x)=1/x for x0 and f(0)=0 is not locally integrable.
