| Popis: | The author generalizes a result concerning the approximation of differences of certain subharmonic functions in \(\mathbb{C} = \mathbb{R}^2\) by the logarithm of the modulus of a meromorphic function to the higher dimensional case. The main result is: Let \(u\) be the difference of subharmonic functions in \(\mathbb{C}^n\) such that \[ |u(z) |\leq c (\varepsilon) |z |^{\rho + \varepsilon} \] \(0 < \rho < 2\), for any \(\varepsilon > 0\) outside a countable union of balls with finite sum of radii, then there are entire functions \(L_1\), \(L_2\) such that outside a \(C_0\)-set \[ \bigl |u(z) - \ln |L_1 (z)/L_2 (z) |\bigr |\leq C \bigl( \ln |z |\bigr)^3 |z |^{\rho (1 - 1/2n}). \] This result is applied to the representation of analytic functions in several variables by exponential series. |
