Abstract

top
Let G be a locally compact abelian group and C V p ( G ) ( 1 ≤ p ≤ 2 ) be the space of bounded convolution operators: L p ( G ) → L p ( G ) . We generalize to C V p ( G ) some results which are well known for C V 2 ( G ) (or rather for L ∞ ( G ^ ) ): we define and study “invariant means” on C V p ( G ) , and we show that if E ⊂ G is compact and scattered the space C V p ( E ) (convolution operators which are supported on E ) has the Schur property and is the norm closure of finitely supported measures. We also give some consequences of these results.
