Abstract
Let u be a subharmonic in Rm, m≥3, function of the zero kind with Riesz measure μ on negative axis Ox1, n(r,u)=μ({x∈Rm:|x|≤r}), N(r,u)=(m−2)∫r1n(t,u)/tm−1dt, ρ(r) is a proximate order, ρ(r)→ρ as r→+∞, 0<ρ<1. We found the asymptotic of u(x) as |x|→+∞ by the condition N(r,u)=(1+o(1))rρ(r), r→+∞. We also investigated the inverse relationship between a regular growth of u and a behavior of N(r,u) as r→+∞.
