Pointwise lower bounds in growth spaces with little o conditions

Complex Variables 2025-07-01 v2 Functional Analysis

Abstract

Pointwise lower bounds on the open unit disc \bbD\bbD for the sum of the moduli of two analytic functions ff and gg (or their derivatives) are known in several cases, like f,gf,g belonging to the Bloch space \cB\cB, BMOABMOA or the weighted Hardy space HωH_\omega^\infty. We find complementary results of Ramey-Ullrich and Abakumov-Doubtsov for functions with little o conditions.
