Наличие параметра 𝑎 &gt; 0 при 𝑎 ̸= 2 приводит к появлениюдеформационных свойств, например, для функций из пространства Шварца обобщенное преобразование Фурье может не быть бесконечно дифференцируемым или быстро убывающим на бесконечности. В случае последовательности 𝑎=2/(2𝑟+ 1), 𝑟 ∈ Z+, деформационные свойства обобщенного преобразования Фурье весьма слабые и после некоторой замены переменных они исчезают. Получаемое унитарное преобразование при 𝑟 = 0 дает обычное преобразование Данкля и обладает многими его свойствами. Оно названо обобщенным преобразованием Данкля. В работе определен оператор сплетения, устанавливающий связь дифференциально-разностного оператора второго порядка, для которого ядро обобщенного преобразования Данкля является собственной функцией, с одномерным оператором Лапласа и позволяющий записать ядро в удобном для его оценок виде. В отличие от оператора сплетения для преобразования Данкля он имеет ненулевое ядро. В работе также на основе свойств обобщенного преобразования Данкля устанавливаются свойства(𝑘, 𝑎)-обобщенного преобразования Фурье при 𝑎=2/(2𝑟 + 1).</p></abstract><trans-abstract xml:lang="en"><p>In harmonic analysis on a line with power weight, the unitary Dunkl transform first appeared.It depends on only one parameter 𝑘 ⩾ 0. Then the two-parameter (𝑘, 𝑎)-generalized Fourier transform appeared, a special case of which is the Dunkl transform (𝑎 = 2). The presence of the parameter 𝑎 &gt; 0 at 𝑎 ̸= 2 leads to the appearance of deformation properties. Forexample, for functions in Schwarz space, the generalized Fourier transform may not be infinitely differentiable or decay rapidly at infinity. In the case of the sequence 𝑎=2/(2𝑟 + 1), 𝑟 ∈ Z+, the deformation properties of the generalized Fourier transform are very weak and after some change of variables they disappear. The resulting unitary transform for 𝑟 = 0 gives the usual Dunkl transform and has many of its properties. It is called the generalized Dunkl transform.We define the intertwining operator that establishes a connection between the second-order differential-difference operator, for which the kernel of the generalized Dunkl transform is an eigenfunction, and the one-dimensional Laplace operator and allows us to write the kernel in a form convenient for its estimates. Unlike the intertwining operator for the Dunkl transform,it has a nonzero kernel. In the paper, also on the basis of the properties of the generalized Dunkl transform, the properties of the (𝑘, 𝑎)-generalized Fourier transform for 𝑎 = 2/(2𝑟 + 1) are established.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>(𝑘</kwd><kwd>𝑎)-обобщенное преобразование Фурье</kwd><kwd>обобщенное преобразование Данкля</kwd><kwd>оператор обобщенного сдвига</kwd><kwd>свертка</kwd><kwd>обобщенные средние.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>(𝑘</kwd><kwd>𝑎)-generalized Fourier transform</kwd><kwd>generalized Dunkl transform</kwd><kwd>generalized translation operator</kwd><kwd>convolution</kwd><kwd>generalized means.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда (проект № 23-71-30001) в МГУ им.
