In the present paper, we investigate approximation of analytic functions and their derivatives in a bounded simply connected domain by the sequences of linear operators without the properties ofâ€¦ (More)

Riesz-Bessel singular integral operators generated by generalized shift operator in weighted HÃ¶lder space H Î³ Î±,Î² is studied. The H Î³ Î±,Î² bounded-ness of this operator is established in certain cases.

We establish two inequalities of Stein-Weiss type for the Riesz potential operator IÎ±,Î³ (Bâˆ’Riesz potential operator) generated by the Laplace-Bessel differential operator Î”B in the weighted Lebesgueâ€¦ (More)
