Research Article


Using inverse Fourier–Jacobi transform two symbols are defined and two pseudo-differential operators (p.d.o.’s) \(\mathcal {P}_{\alpha ,\beta }(x,D) \) and \(\mathsf {Q}_{\alpha ,\beta } (x,D) \) are introduced. Composition of \(\mathcal {P}_{\alpha ,\beta }(x,D) \) and \(\mathsf {Q}_{\alpha ,\beta } (x,D) \) is defined. It is shown that the p.d.o.’s and composition of p.d.o.’s are bounded in a Sobolev type space. Some special cases are discussed.
