Abstract

We provide a characterization of $J$-class and $J^{mix}$-class unilateralweighted shifts on $l^{\infty}(\mathbb{N})$ in terms of their weight sequences.In contrast to the previously mentioned result we show that a bilateralweighted shift on $l^{\infty}(\mathbb{Z})$ cannot be a $J$-class operator.
