Notes on the results of lower bounds for a class of harmonic functions in the half space

Abstract

Using changes of Poisson-Sch measure with respect to a cone developed by Huang and Ychussie (Filomat, 30(12), 2016) from another point of view, we point several gaps in the paper ``On the lower bound for a class of harmonic functions in the half space" by Zhang, Deng and Kou (Acta Math. Sci. Ser. B Engl. Ed., 32(4), 2012) and give the main results under weaker conditions.
