Conformality in the sense of Gromov and holomorphicity

M. Gromov extended the notion of conformal mapping, making it applicable for mappings of spaces of different dimensions. For example, any entire holomorphic function $f\colon{\mathbb C}^n \to {\mathbb C}$ defines a mapping conformal in the sense of Gromov. We will recall the required definition and note that not every conformal mapping in the sense of Gromov is a holomorphic one. We will give a criterion for its holomorphicity and discuss some related new concepts and facts.
