利用半序方法在u0-r完备的Archimedean型向量格中讨论格增算子不动点问题,在条件不同的情况下得到了不动点的存在唯一性定理及迭代序列的收敛性.
In this paper,by using the partial order method,the lattice of increasing operators are studied in u0-r complete Archimedean vector lattice.we obtain the existence and uniqueness of the fixed point by adding different conditions,as well as the convergence of the iterative sequence.
