摘要
提出了 3N + 1猜想的压缩迭代 ,给出了该迭代下的某些结果 .这些结果是 :关于 3N + 1猜想的 3个等价命题 ;叙拉古阶序列 ;n的项公式及证明 ;关于系数停止次数tc(n)与足够停止次数ta(n)相等的两个定理 .3N +
The concept of contractible iteration for the 3N+ 1 conjecture was presented. The results of contractible iteration were given as fo llows: some equivalence propositions for the 3N+1 conjecture; sequence of Sy racuse order; proof of term formula of n; some theories about t a(n)= t c(n).
