The study of differential operators within the framework of Lie groups offers a profound gateway into understanding symmetry, geometry and representation theory. At its core, this area investigates ...

Pseudo-differential operators have emerged as pivotal tools in modern analysis, generalising classical differential operators to encapsulate non-local behaviour via their symbol calculus. Their ...

We consider the polynomials {Lα, M n(x, l)}∞ n = 0 orthogonal with respect to the Sobolev type inner product $\langle p, q\rangle = \frac{1}{\Gamma (\alpha + 1 ...
