Composition of entire function and analytic functions in the unit ball with a vanished gradient by A. I. Bandura, T. M. Salo, O. B. Skaskiv

“…The obtained results complement earlier published results with $\mathop{grad}\Phi(z)=(\frac{\partial \Phi(z)}{\partial z_1}, \ldots, \frac{\partial \Phi(z)}{\partial z_j},\ldots,\frac{\partial \Phi(z)}{\partial z_n})\ne \mathbf{0}.$ Also, we study a more general composition $H(\mathbf{w})=G(\mathbf{\Phi}(\mathbf{w}))$, where $G: \mathbb{C}^n\to \mathbb{C}$ is an entire function of the bounded $\mathbf{L}$-index in joint variables, $\mathbf{\Phi}: \mathbb{B}^m\to \mathbb{C}^n$ is a vector-valued analytic function, and $\mathbf{L}: \mathbb{C}^n\to\mathbb{R}^n_+$ is a continuous function. …”
