Now, it follows easily that any simple function ∑ i = 1 n c i χ A i, where each A i has finite measure, can also be approximated by a compactly supported continuous function. Since this kind of simple functions are dense in L p (X) we see that C c (X) is also dense in L p (X).

https://en.wikipedia.org/wiki/Sobolev_space
In mathematics, a Sobolev space is a vector space of functions equipped with a norm that is a combination of L p-norms of the function together with its derivatives up to a given order. The derivatives are understood in a suitable weak sense to make the space complete, i.e. a Banach space.Intuitively, a Sobolev space is a space of functions possessing sufficiently many derivatives for some ...

i 6= 0, meaning that its support has nite measure. On the other hand, every simple function belongs to L1. For suitable measures de ned on topological spaces, Theorem 7.8 can be used to prove the density of continuous functions in Lp for 1 p<1, as in Theorem 4.27 for Lebesgue measure on Rn. We will not consider extensions of that result to more

then the support of f is the closed interval [−1,1], since f is non-zero on the open interval (−1,1) and the closure of this set is [−1,1].. 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.
