摘要
给出了以Fuzzy数作为Lipschitz常数的压缩映射新概念,并证明了Fuzzy数值函数的不动点定理.定理4设AF(R)为完备子集,f为A上的Fuzzy压缩映射且Lispchitz常数α满足条件0<α<1supλ∈(0,1]α+λ<1则f在A上有唯一不动点x0,且对y∈A。
definition of Fuzzy contraction mapping with Fuzzy contraction constant number is given.And the fixed point theorem for Fuzzy contraction mapping is obtained.
