Abstract

In the paper, we introduce the concept of weight with reasonable growth on a locally compact group GG. We verify that these weights form a natural class to work with, by examining the most common examples. We proceed with the discussion of the LpL^p-conjecture. With the use of Riesz-Thorin-Stein-Weiss interpolation, we establish that \mbox{Lωp(G)Lωp(G)Lωp(G)L^p_{\omega}(G)\star L^p_{\omega}(G)\subset L^p_{\omega}(G)}, p>1p>1 implies that Lωp(G)Lωq(G)Lωq(G)L^p_{\omega}(G)\star L^q_{\omega}(G)\subset L^q_{\omega}(G) for qq which lies between pp and pp'. At last, we confirm the LωpL^p_{\omega}-conjecture for weights of (p,q)(p,q)-reasonable growth.
