论文摘要
我们表征了两个非阴性整数的两个类似collatz型二次映射的所有有界轨道。在一个情况下,如果可能发生所有可能的长度的循环,则仅当轨道达到周期时才有界限。对于其他地图,我们证明每个有限的轨道都必须达到0(特别是没有周期)。
We characterize all bounded orbits of two similar Collatz-type quadratic mappings of the set of non-negative integers. In one case, where cycles of all possible lengths may occur, an orbit is bounded if and only if it reaches a cycle. For the other map we prove that every bounded orbit must reach 0 (in particular, there are no cycles).
