Abstract

Let \(p\) be a real number greater than one and let \(\Gamma\) be a graph of bounded degree. We investigate links between the \(p\)-harmonic boundary of \(\Gamma\)and the \(D_p\)-massive subsets of \(\Gamma\). In particular, if there are \(n\) pairwise disjoint \(D_p\)-massive subsets of \(\Gamma\), then the \(p\)-harmonic boundary of \(\Gamma\) consists of at least \(n\) elements. We also show that the converse of this statement is also true. 10.1017/S0004972713000439
