Abstract
Let $D$ be a strictly pseudoconvex domain and $X$ be a singular analytic set of pure dimension $n-1$ in $\mathbb{C} ^n$ such that $X\cap D\neq \emptyset $ and $X\cap bD$ is transverse. We give sufficient conditions for a function holomorphic on $D\cap X$ to admit a holomorphic extension which belongs to $L^q(D),$ $q\in [1,+\infty [$, or to ${\rm BMO} (D)$. The extension is given by means of integral representation formulas and residue currents.
