摘要
讨论了第一个指数大于1,第二个指数不小于0和第一个指数在0到1之间,第二个指数不小于0指数情形不等式条件下凸幂凝聚算子不动点的存在性,得到了几个新的结论,推广和补充了Altman型不动点定理。
The existence of fixed points about convex-power condensing operator is discussed under the inequality conditions in which the first exponent is respectively greater than 1 and between 0 and 1, the second exponem is not less than O. Some new conclusions are obtained which extend and supplement the fixed point theorems of Altman type.
