Spectral synthesis, translation invariant subspace of $L^2(G)$, Plancherel theorem
Abstract :
[en] For locally compact, second countable, type I groups
$G$, we characterize all closed (two-sided) translation invariant
subspaces of $L^2(G)$. We establish a similar result for
$K$-biinvariant $L^2$-functions ($K$ a fixed maximal compact
subgroup) in the context of semisimple Lie groups.
