This paper focuses on representations of contractively embedded invariant subspaces in several variables.We present a version of the de Branges theorem for n-tuples of multiplication operators by the coordinate functions on analytic reproducing kernel Hilbert spaces over the unit ball \(\mathbb{B}^{n}\) and the Hardy space over the unit polydics \(\mathbb{D}^{n}\) in \(\mathbb{C}^{n}\).


Invariant subspaces de Branges–Rovnyak spaces Hardy space reproducing kernel Hilbert spaces multipliers bounded analytic functions
