摘要
研究了隐式模糊微分方程初值问题和边值问题{x'(t)=f(t,x(t),x'(t)),t∈[0,T]x(0)=x0,x0 ∈E 和{x'(t)=f(l,x(t),x'(t))x(0)=λx(T),x(0)∈ E的解的存在唯一性.基于强广义微分给出隐式模糊微分方程的积分等价形式,利用广义压缩映射原理证明解的存在唯一性,最后给出了具体的算例验证其合理性.
Abstract
In this paper,we study the existence and uniqueness of solutions for the following implicit fuzzy differential equation initial value problem and boundary value problem.{x'(t)=f(t,x(t),x'(t)),t ∈[0,T]x(0)=x0,x0 ∈ E and {x'(t)=f(t,x(t),x'(t))x(0)=λx(T),x(0)∈ E Based on the strong generalized differential,the integral equivalent form of implicit fuzzy differential equation is given,and the existence and uniqueness of the solution is proved by using the principle of generalized contractive mapping.Finally,a specific example is given to verify its rationality.
