Abstract: Let $ M$ be an invariant subspace of the Bergman space $ L_a^2(\mathbb{D})$ and $ S_M$ be the compression of the coordinate multiplication operator $ M_z$ to the co-invariant subspace $ L_a^2(\mathbb{D})\ominus M$. The present paper determines when the identity representation of $ C^*(S_M)$ is a boundary representation for the Banach subalgebra $ \mathcal{B}(S_M)$. The paper also considers boundary representations on the co-invariant subspaces of $ L_a^2(\mathbb{B}_n)$.
