隨著科學(xué)技術(shù)的發(fā)展,非局部抽象柯西問(wèn)題解的存在性已在很多文章中被深入研究過(guò)。非局部抽象柯西問(wèn)題它在物理、經(jīng)濟(jì)、通訊等領(lǐng)域都有著廣泛的應(yīng)用前景;同時(shí),研究方法涉及到泛函分析、常微分方程、偏微分方程等基礎(chǔ)數(shù)學(xué)理論,有著廣泛的理論意義。帶非局部初值的初值問(wèn)題最早是在Byszweki[1]提出來(lái)的,后來(lái)許多學(xué)者利用不同的不動(dòng)點(diǎn)定理證明其解的存在性。本文通過(guò)定義映射,用兩個(gè)不動(dòng)點(diǎn)定理的引理來(lái)證明其解在Banach空間中的存在性。
