Almost periodic distributions in a tube domain

A notion of an almost periodic (a.p.) distribution in a tube domain $T_G$ in $C^n$ is introduced. Properties of such distributions are investigated, some of them are similar to the properties of ordinary a.p. functions on the axis. In these terms the notion of an a.p. divisor in $T_G$ is introduced, and conditions for the existence of density of such a divisor in $T_{G'}$, $G'\Subset G$, are found.
