Distributions Defined by Divergent Integrals
In the previous chapters we have defined various singular distributions. One of them is Pf(l/x), defined in Example 4 of Section 2.4. The function 1/x is not integrable on any neighborhood of the origin. We succeeded in regularizing this function by defining the functionalPf (l/x) by the principal value of the singular integral defined by the quantity (φ, 1/x). The aim of this chapter is to extend this idea and to regularize various singular integrals and thereby define the coresponding distributions. Let us start with a simple example.
