Integral operator defined on $two$ distinct dense subspaces

I have decided to edit my post a bit heavily for clarity. I was trying to be fairly general but it's hard to see what I'm asking so I've decided to limit myself to a specific example which will hopefu …

Inverse Hankel Transform

I was reading through Akhiezer's book Lectures on Integral Transforms and in chapter nine, he states that the Hankel transform is unitary for $\nu > -1$, so that for a suitable function, $f$, $f(y) = …

Motivating the Bessel translation operator

After some thought, I decided to see what happens in the Fourier case. Since $j_{\alpha}$ is an eigenfunction of $D_{\alpha}$, it stood to reason that we should look to the following PDE in the Fourie …

Motivating the Bessel translation operator

In a paper I am reading on the Hankel transform (this paper to be exact), I've come across a somewhat peculiar definition for a generalized translation operator. The operator is designed with a convol …
