Abstract
My objective is to define non-archimedean pseudo-differential operator associted with fractional Fourier transform in this manuscript. In this manuscript, we discuss some classes of \(\mathrm{p}\) -adic complete inner product spaces, \(\mathscr{B}_{\phi, k}\left(Q_p\right), \quad 0 \leq k<\infty\) , connected to negative definite, radial and continuous functions \(\phi: \mathbb{Q}_p \rightarrow \mathbb{C}\). In this article, we also introduce the non-archimedean pseudo-differential operator \(\mathscr{A}_{\phi k}\) involving fractional Fourier transform connected to negative definite functions. We| find the convolution Kernel \(\mathscr{K}_k\) of these operators and the Green function related to fractional Fourier transform.
Keywords: Non-archimedean analysis, Pseudo-differential operators, Fractional Fourier transform, M-dissipative operators
