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 ...

Operator theory and analytic function spaces form a rich interface between functional analysis, complex analysis and mathematical physics. At its core, operator theory studies linear maps on Hilbert ...

(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 ...

A prefix operator is an operator that is applied to the variable, constant, function, or parenthetic expression that immediately follows it. The plus sign (+) and minus sign (-) can be used as prefix ...
