Composition and Commutator of Singular -Pseudodifferential Kipriyanov Operators in.

The paper introduces integral transformations for studying problems with a singular differential Bessel operator with a negative parameter . We construct the -Bessel transform and the corresponding class of singular -pseudodifferential operators. A theorem on the order of -pseudodifferential operators in a special class of Sobolev–Kipriyanov functions is proved. [ABSTRACT FROM AUTHOR]
