Abstract: We prove the reducibility of analytic multipliers $M_\phi$ with a class of finite Blaschke products symbol $\phi$ on the Sobolev disk algebra $R(\mathbb{D})$. We also describe their nontrivial minimal reducing subspaces.

Key words: Reducing subspace, multiplier, finite Blaschke product, Sobolev disk algebra
