An operator theory approach to the evanescent part of a two-parametric weak-stationary stochastic process

Zbigniew Burdak, Marek Kosiek, Patryk Pagacz +1

A new approach to the evanescent part of a two-dimensional weak-stationary stochastic process with the past given by a half-plane is proceed. The classical result due to Helson and…
