关于离散调和函数唯一延拓的注记

A note on unique continuation for discrete harmonic functions

Maru Guadie, Eugenia Malinnikova

摘要:

本文给出了以下简单观察的一个定量形式:格点上的离散调和函数可以在大立方体的每一点处为零而不全同为零,同时,由于离散调和函数在大尺度上类似于连续函数,因此存在一个关于离散调和函数的三球定理.

英文摘要:

In this note we give a quantitative version of the following simple observation: a discrete harmonic function on the lattice may vanish at each point of a large cube without being zero identically, at the same time there is a version of three balls theorem for discrete harmonic functions since they resemble continuous ones on large scales.
