Настоящее продолжение этой статьи посвящено вычислению матричных элементов тождественного оператора T(e) и операторов представления T(g) для подходящих элементов g группы относительно смешанного базиса, соответствующего двум различным базисам пространства представления, и вычислению некоторых несобственных интегралов, содержащих произведение функций Бесселя–Клиффорда и Уиттекера. Полученные результаты могут быть переписаны на языке интегральных преобразований Ганкеля–Клиффорда и их аналога. Первое и второе преобразования Ганкеля–Клиффорда, введенные сооответственно Хайеком и Перезом–Робайной, играют важную роль в теории дифференциальных операторов дробного порядка (см., например, [6, 8]). Близкий результат получен авторами недавно [<xref ref-type="bibr" rid="cit12">12</xref>] для регулярной кулоновской функции.</p></abstract><trans-abstract xml:lang="en"><p>In [<xref ref-type="bibr" rid="cit11">11</xref>], the authors considered the realization T of SO(2, 2)-representation in a space of homogeneous functions on 2×4-matrices. In this sequel, we aim to compute matrix elements of the identical operator T(e) and representation operator T(g) for an appropriate g with respect to the mixed basis related to two different bases in the SO(2, 2)-carrier space and evaluate some improper integrals involving a product of Bessel-Clifford and Whittaker functions. The obtained result can be rewritten in terms of Hankel-Clifford integral transforms and their analogue. The first and the second Hankel-Clifford transforms introduced by Hayek and Pérez–Robayna, respectively, play an important role in the theory of fractional order differential operators (see, e.g., [6, 8]). The similar result have been derived recently by the authors for the regular Coulomb function in [<xref ref-type="bibr" rid="cit12">12</xref>].</p></trans-abstract></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Abramowitz M.
