Stability of trigonometric approximation in $L^p$ and applications to prediction theory

Lutz Klotz, Michael Frank

Let $\Gamma$ be an LCA group and $({\mu }_n)$ be a sequence of bounded regular Borel measures on $\Gamma$ tending to a measure ${\mu }_0$. Let $G$ be the dual group of $\Gamma$, $S$ be a non-empty subset o…
