Example text

3 If T ∈ ′, then T is said to be zero in an open set Ω ⊂ Rn if 〈T, 〉 = 0 for all ∈ (Ω) where (Ω) is the space of C functions with compact support lying in Ω. The union of all open Ω where T = 0 is open and its complement is defined as the support of T (written supp T or T). Thus supp T is the smallest closed set outside of which T = 0 and x ∈ supp T if T ≠ 0 in any open nbh of x. 4 ′ is the space of distributions T ∈ ′ with compact support. Proof Let T ∈ ′ with supp T compact and let k → 0 in .

These two spaces have duals ′ and ′ which are the space of distributions with compact support and the natural domain for the Fourier transform respectively. First we deal with ′. 3 If T ∈ ′, then T is said to be zero in an open set Ω ⊂ Rn if 〈T, 〉 = 0 for all ∈ (Ω) where (Ω) is the space of C functions with compact support lying in Ω. The union of all open Ω where T = 0 is open and its complement is defined as the support of T (written supp T or T). Thus supp T is the smallest closed set outside of which T = 0 and x ∈ supp T if T ≠ 0 in any open nbh of x.

Hence we have shown T ⊃ T′ for any locally convex topology T′ on for which im is continuous, since any T′ nbh U is also a T nbh (T ⊃ T′ means T is finer than T′ or T′ is coarser than T). 2. As an exercise (Exercise 4) show that if is another sequence of compact sets exhausting Rn, then will have the same topology if it is constructed as above using the . Hence we shall always think of some fixed sequence Km defining . 1 with the topology T just described is called the strict inductive limit of the m and denoted by .
