基于李善兰考数根法原始文献的解读,将其解译为素数判定的数学定理,并表述为完整的现代数学符号语言。认为其等价于费马小定理,其素数判定的方法可解析为:屡乘求一、天元求一、小数回环、准根分级4种方法,进而将其具体分解为减少结算量而求定次d,李善兰给出了素数判定的充分必要条件。
Based on interpretation original documents about the kao shugen laws of Li Shan-lan,which is interpreted as the mathematical theory of prime numbers,and expressed as a complete language of modern mathematical symbols.It is equivalent to Fermat's small theorem.Its mathematical judgment methods of prime numbers be classified:nu-cheng find one method,tian-yuan find one method,xiao-shu loop back method,quasi-root classification method,then reduce the amount to break for the sake of its specific set times d,ultimately gave the necessary and sufficient conditions of the judgment methods of prime numbers.
