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 ...

Schrödinger operator theory in function spaces examines the mapping properties and spectral behaviour of operators of the form L = –Δ + V, where Δ denotes the Laplace operator and V a nonnegative ...

(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 ...
