Summary:
In this paper, we study the finite Hankel transformation on spaces of ge\-ne\-ra\-lized functions by developing a new procedure. We consider two Hankel type integral transformations $h_\mu$ and $h_\mu ^{\ast }$ connected by the Parseval equation $$\sum_{n=0}^{\infty }(h_\mu f)(n)(h_\mu ^{\ast } \varphi )(n)= \int_{0}^{1}f(x)\varphi (x)\, dx.$$ A space $S_\mu$ of functions and a space $L_\mu$ of complex sequences are introduced. $h_\mu ^{\ast }$ is an isomorphism from $S_\mu$ onto $L_\mu$ when $\mu \geq -\frac{1}{2}$. We propose to define the generalized finite Hankel transform $h'_\mu f$ of $f\in S'_\mu$ by $$\langle (h'_\mu f), ((h_\mu ^{\ast } \varphi )(n))_{n=0}^{\infty }\rangle =\langle f,\varphi \rangle, \quad \text{for } \varphi \in S_\mu .$$
