Characterization of generalized Hankel integral type transformable generalized functions. (English) Zbl 1030.46052
The first author, in 2000, has discussed a generalized Hankel-type transformation defined by $F(y)= \biggl(F_{1, \mu,\alpha,\beta, \nu} \bigl\{f(x) \bigr\}\biggr) (y)=\nu\beta y^{-1-2\alpha+2 \nu}\int^\infty_0 (xy)^\alpha J_\mu \bigl[\beta (xy)\bigr]^\nu f(x)dx$ where $$\alpha,\beta,\nu$$ are real and $$J_\mu(z)$$ is the Bessel function of first kind and of order $$\mu$$. He also extended the results to a class of generalized functions.
Similar to the spaces of $$H_\mu$$ [A. H. Zehmanian, Generalized integral transformations, Chapter V, New York: Wiley (1968; Zbl 0181.12701)] the spaces $$H_{1,\mu, 1/2,1}$$, $$H_{2,\mu,1/2,1}$$ and their duals are defined in a paper by the first author and Bandewar (to appear).
In the paper under review, the authors proved a characterization theorem for generalized Hankel-type transformable generalized functions in $$H_{2,\mu, \alpha,\beta, \nu}'$$. They also maintain that similar results can be deduced for elements of the space $$H_{1,\mu,\alpha, \beta,\mu}'$$.
