正三角形网格中变换下的电阻值

Resistance values under transformations in regular triangular grids

Emily J. Evans, Russell J. Hendel

AI总结:

本文拓展了三角网格电阻距离的相关研究,通过等效电路逐行约简分析非渐近电阻行为,提出并证明了电阻值与1大小关系猜想的特例,还发现了约简后对角线上的重复电阻模式,同时优化了相关符号与证明方法。

摘要:

在[Evans, Francis 2022; Hendel]的研究中,作者们探究了三角网格图中的电阻距离,并观察到了多种渐近行为。本文通过研究执行等效电路变换时出现的初始非渐近行为,拓展了他们的工作,该变换会逐行减少三角网格图的行数。核心猜想刻画了:对所有边电阻均恒为1的初始三角网格进行任意次数约简后,边电阻值小于、等于或大于1的情形。该猜想的一个特例已得到证明。主要定理指出,若原始网格至少有4s行三角形,则经过s次约简的三角网格的对角线上会出现重复的边电阻模式。本文还改进了此前作者们提出的符号体系、概念和证明技巧。

英文摘要:

In [Evans, Francis 2022; Hendel] the authors investigated resistance distance in triangular grid graphs and observed several types of asymptotic behavior. This paper extends their work by studying the initial, non-asymptotic, behavior found when equivalent circuit transformations are performed, reducing the rows in the triangular grid graph one row at a time. The main conjecture characterizes, after reducing an arbitrary number of times an initial triangular grid all of whose edge resistances are identically one, when edge resistance values are less than, equal to, or greater than one. A special case of the conjecture is proven. The main theorem identifies patterns of repeating edge resistances arising in diagonals of a triangular grid reduced $s$ times provided the original grid has at least $4s$ rows of triangles. This paper also improves upon the notation, concepts, and proof techniques introduced by the authors previously.
