The Dunkl transform is a sophisticated generalisation of the classical Fourier transform, incorporating differential‐difference operators that are defined in relation to reflection groups. This ...

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 ...

The differential operator ring S = R[ x; δ ] can be embedded in A1(R), the first Weyl algebra over R, where R is a Q-algebra and δ is a locally nilpotent derivation on R. Furthermore A1(R) is again a ...
