“…. , γ k > 0 have been investigated by many researchers, see Muckenhoupt and Stein [13], Kipriyanov [10], Trimeche [18], Lyakhov [12], Stempak [17], Gadjiev and Aliev [2], Guliyev [3,4,5,6], Guliyev and Hasanov [7], Guliyev, Serbetci and Ekincioglu [9], and others. In this paper we consider the generalized shift operator generated by the Laplace-Bessel differential operator Δ B in terms of which we study the boundedness of the modified B-Riesz potential e I α,γ in the limiting case.…”
