摘要

我们研究了在模函数空间Lρ的设置下Fredholm积分方程Φ(Φ)=G(Φ，Φ(Φ))+∫01F(Φ，ζ，Φ(ζ))dζ解的存在性，对于Φ∈[0,1]。在指数函数p(·)和函数F、G的特定条件下，在变指数Lebesgue空间Lp(·)的框架内推导了本研究的一个应用。

Examining Nonlinear Fredholm Equations in Lebesgue Spaces with Variable Exponents

We investigate the existence of solutions for the Fredholm integral equation Φ(ϑ)=G(ϑ,Φ(ϑ))+∫01F(ϑ,ζ,Φ(ζ))dζ, for ϑ∈[0,1], in the setting of the modular function spaces Lρ. We also derive an application of this research within the framework of variable exponent Lebesgue spaces Lp(·) subject to specific conditions imposed on the exponent function p(·) and the functions F and G.
