我们刻画了允许有限能量的非常数调和函数的局部有限网络。我们的刻画统一了J.B. Assen(J ComB Theory,Ser B 49:87-102,1990)和里昂和佩雷斯(2011)的必要存在性判据与Soardi(1991)的充分判据。我们还扩展了Georgakopoulos(J Lond Math Soc,2010)的有限能量的非难以捉摸的非常数调和函数的必要存在性准则。
We characterize the locally finite networks admitting non-constant harmonic functions of finite energy. Our characterization unifies the necessary existence criteria of Thomassen (J Comb Theory, Ser B 49:87–102, 1990) and of Lyons and Peres (2011) with the sufficient criterion of Soardi (1991). We also extend a necessary existence criterion for non-elusive non-constant harmonic functions of finite energy due to Georgakopoulos (J Lond Math Soc, 2010).
