Abstract: The spaces Hα,δ,γ((a, b)×(a, b), ℝ) and Hα,δ((a, b), ℝ) were defined in ((Hüseynov (1981)), pages 271–277). Some singular integral operators on Banach spaces were examined, (Dostanic (2012)), (Dunford (1988), pages 2419–2426 and (Plamenevskiy (1965)). The solutions of some singular Fredholm integral equations were given in (Babolian (2011), Okayama (2010), and Thomas (1981)) by numerical methods. In this paper, we define the sets Hα,δ,γ((a, b)×(a, b), X) and Hα,δ((a, b), X) by taking an arbitrary Banach space X instead of ℝ, and we show that these sets which are different from the spaces given in (Dunford (1988)) and (Plamenevskiy (1965)) are Banach spaces with the norms ∥·∥α,δ,γ and ∥·∥α,δ. Besides, the bounded linear integral operators on the spaces Hα,δ,γ((a, b)×(a, b), X) and Hα,δ((a, b), X), some of which are singular, are derived, and the solutions of the linear Fredholm integral equations of the form f(s)=ϕ(s)+λ∫abA(s,t)f(t)dt,f(s)=ϕ(s)+λ∫abA(t,s)f(t)dt and f(s,t)=ϕ(s,t)+λ∫abA(s,t)f(t,s)dt are investigated in these spaces by analytical methods.
