摘要
Abstract
The paper provides two new points of view at the problem of 3n +-1.One is a place shift problem demonstrating that the operations involved in the problem of 3n + 1 and its generalizations are equivalent to shifting sequences of digits expressed in a number system with a proper base.The other one is a problem about the existence of a particular hypothetical graph for the number theoretical function of the problem of 3n + 1.Some new discoveries about the problem and its generalizations are presented in the paper.These include the phenomenon that the majority of the numbers entering the final cycle through the number 5 on the classical problem of 3n +1 and the phenomenon that the majority of the numbers entering a specific cycle on a generalized problem in the number system with base 3.关键词
