Streszczenie
We first show that a linear operator which is bounded on $L^2_w$ with $w\in A_1$ can be extended to a bounded operator on the weighted local Hardy space $h^1_w$ if and only if this operator is uniformly bounded on all $h^1_w$-atoms. As an application, we show that every pseudo-differential operator of order zero has a bounded extension to $h^1_w$.
