Abstract
We deal with several classes of integral transformations of the form
, where D is an operator. In case D is the identity operator, we obtain several operator properties on L p (ℝ+) with weights for a generalized operator related to the Fourier cosine and the Kontorovich-Lebedev integral transforms. For a class of differential operators of infinite order, we prove the unitary property of these transforms on L 2(ℝ+) and define the inversion formula. Further, for an other class of differential operators of finite order, we apply these transformations to solve a class of integro-differential problems of generalized convolution type.
