Abstract

In this paper, we introduce a family of integral transforms, denoted by Oα\mathcal{O}_{\alpha}, and constructed via kernel fusion of the fractional Fourier transform (FRFT) with angle απZ\alpha \notin \pi \mathbb{Z}. We demonstrate that the Oα\mathcal{O}_{\alpha}-transformation constitutes a well-defined integral operator by establishing its basic operational properties. Besides, we survey various mathematical aspects of the uncertainty principles for the Oα\mathcal{O}_{\alpha}-transform, including Heisenberg's inequality, logarithmic uncertainty inequality, local uncertainty inequality, Hardy's inequality, Pitt's inequality, and Beurling-H{\"o}rmander's theorem.
