Hausdorff operators form a class of linear integral transforms characterised by a kernel function and a dilation parameter that together encode scaling and averaging effects on input functions.

Pseudodifferential operators extend the classical theory of partial differential operators by incorporating phase-space symbols that encode both spatial and frequency behaviour. Originating in the ...

(Phys.org)—Researchers have discovered that the solutions to a famous mathematical function called the Riemann zeta function correspond to the solutions of another, different kind of function that may ...
