Abstract

In this paper, we prove that σ-compactness of a locally compact group G is a necessary condition for the weighted Orlicz space to be a convolution algebra, and for a class of Orlicz spaces we give an equivalent condition. Also, we show that if is -invariant, then there exists a constant c > 0 such that Φ(ω(st)) ≤ c ω(s)ω _Φ (t) for locally a.e. s, t ∈ G, where ω _Φ is a locally integrable function satisfying an inclusion property.
