Abstract

It is proved that the lower types of functions $T(r, u)$ and $N(r, u) = N(r, u_1) + N(z, u_2)$ relative to the proximate order $ρ(r)$ of a function $u=U_1−u_2$ of fractional order $ρ δ$-subharmonic in $ℝ^m, m > - 2,$ coincide, that is, are simultaneously minimal or mean. In the case of an arbitrary proximate order $ρ(r)$, the assertion is, in general, false.
