Abstract

A bounded linear operator TT on a Banach space XX (not necessarily separable) is said to be JJ-class operator whenever the extended limit set, say JT(x)J_T(x) equals XX for some vector xXx\in X. Practically, the extended limit sets localize the dynamical behavior of operators. In this paper, using the extended limit sets we will examine the necessary and sufficient conditions for the weighted translation Ta,ωT_{a,\omega} to be JJ-class on a locally compact group GG, within the setting of Lp L^p-spaces for 1p< 1 \leq p < \infty . Precisely, we delineate the boundary between JJ-class and hypercyclic behavior for weighted translations. Then, we will show that for torsion elements in locally compact groups, unlike the case of non-dense orbits of weighted translations, we have JTa,ω(0)=Lp(G)J_{T_{a,\omega}}(0)=L^p(G). Finally, we will provide some examples on which the weighted translation Ta,ω T_{a,\omega} is JJ-class but it fails to be hypercyclic.
