For a given odd positive integer n and an odd prime p, we construct an infinite family of quadruples of imaginary quadratic fields , , and with such that the class number of each of them is divisible by n. Subsequently, we show that there is an infinite family of quintuples of imaginary quadratic fields , , , and with whose class numbers are all divisible by n. Our results provide a complete proof of Iizuka's conjecture (in fact a generalization of it) for the case . Our results also affirmatively answer a weaker version of (a generalization of) Iizuka's conjecture for .

关于饭冢的猜想
文本
对于给定的奇正整数n和奇质数p,我们构造了一个无限的四元组虚二次域,,和和使得它们每个的类号都可以被n整除。随后,我们证明了存在一个无限的五元组虚二次域,,,和和其班级编号都可以被n整除。我们的结果为该案例提供了饭冢猜想(实际上是它的推广)的完整证明. 我们的结果也肯定地回答了 Iizuka 猜想的较弱版本(概括).
