我们考虑了一些由Hurwitz (1887)[7], Lakein(1973)[10]和Shiokawa等(1975)[20]引入的欧几里得场Q(−d), d= 1,2,3,7和11的复连分数展开及其相关映射。我们证明了他们引入的每一类连分数展开式都存在勒让德常数,改进了Ei等人(2019)[4]对A. Hurwitz的Q(−1)展开式的证明。
We consider some types of complex continued fraction expansions and their associated maps of the Euclidean fields Q (− d), d= 1, 2, 3, 7 and 11 introduced by Hurwitz (1887)[7], Lakein (1973)[10] and Shiokawa et al.(1975)[20]. We show that there exists the Legendre constant for every type of continued fraction expansions introduced by them improving the proof by Ei et al.(2019)[4] in the case of the one by A. Hurwitz with Q (− 1).
