Аннотация:
The utility of the (weighted) van der Corput inequalities or of the stationary phase method is illustrated with various examples borrowed from: differentiability issues (Riemann's function and related); functional analysis on Banach spaces or algebras of analytic functions (composition operators); and local Banach space geometry (Schäffer's problem).
Ключевые слова:
stationary phase method, powers of functions, Blaschke factors, Wiener space, Dirichlet series, composition operators, Schäffer's problem, Toeplitz operators.
