Title: The Proof and Practical Significance of the Four Color Conjecture by Using Digital Plate Jigsaw 四色猜想的数字图板拼图证明与实用意义 Name(s): Li Chuanxue 李传学 Abstract: 四色猜想是个封闭曲线事物形态（△□线面同一、曲直等价）连续变换（拓变）且由数论跨学科证明的微分[任意、无（穷x）限→dx=△x]概念问题。数字（色序）“相异相邻、相同（异）对顶”是证明规则。受理性史前文明四个符号（三角形、对顶三角形、方阵形/四方五位、八角星/四方八位）启佑，在运用1、2、3、4数字标记三角形△“1面、3线”“四方五位、四方八位”链锁重组对顶三角形数字图版证明和二阶方阵数字图版表达式证明基础上，同步有六种数字图板拼图（含子阵）模型证明四色猜想。“点、线、面”的数学+历史符号（相关四色猜想）+宇宙“点、线、面”的哲学含义相融，彰显天宇、地球、“人亦大”的万物数学之美。数学模型证明四色猜想“任意”（无穷）、通俗、实用，不存在“飞地”之困，优于计算机“有限”证明。 Key words: 链锁1面3线；四色二阶方阵；相异相邻；四色叠加迭代；四色图版拼图；重组对顶；四色启佑 DOI：10.12424/HA.2023.018 https://dx.doi.org/10.12424/HA.2023.018 https://www.oc-press.com/HA-03-089.html
