A class of mappings is defined and the characterization of the class of all cofinite languages in terms of fixed points of mappings is give
从映射的不动点方面研究了余有限语言的特性。
Based on the partial order theory, Kuratowski measure of noncompactness, fixed point theorem of condensing mapping and the fixed point index theory in cones, the paper discussed the existence of solutions to the Sturm-Liouville problemsin Banach spaces and the main results are as follows:1.
本文利用半序理论，非紧性测度，凝聚映射的不动点定理及锥上的不动点指数理论，讨论了Banach空间E中Sturm-Liouville边值问题 -(p(t)u′(t))′+q(t)u(t)=f(t，u(t))，t∈[0，1] α_0u(0)-β_0p(0)u′(0)=θ，α_1u(1)+β_1p(1)u′(1)=θ，解的存在性，主要结果有： 一、通过建立新的极大值原理，讨论Banach空间中一般的Sturm-Liouville问题解的存在性，在不假定f(t，u)连续，仅假定f(t，u)满足弱Caratheodory条件，运用上下解单调迭代方法，并结合非紧性测度的性质，研究了Sturm-Liouville边值问题最大解与最小解的存在性。
