摘要 利用半序理论研究了Banach空间中一类非线性算子方程组解的存在唯一性,并且给出了解的逼近序列以及误差估计。本文所得的结果改进和推广了相应结果。 By use of partial order theory, the existence, uniqueness and monotone iterative approximation of solutions for a class of systems on nonlinear operator equations in Banach spaces are discussed. The results obtained here improve and generalize the corresponding results.
