Existence of positive solutions for a nonlinear quadratic integral equation. <i>Electronic Journal of Differential Equations, 2019</i>(79), pp. 1-11.1072-6691https://hdl.handle.net/10877/14967In this article, we study the existence of positive solutions for the nonlinear quadratic integral equation x(t) = g(t, x(t)) ∫t-∞ α(t, t - s) ƒ(s, x(s))ds, t ∈ ℝ. By using fixed point theory on cones, we prove the existence and uniqueness of bounded and continuous solution with positive infimum. An example illustrates the abstract result.Text11 pages1 file (.pdf)enAttribution 4.0 InternationalQuadratic integral equationPositive solutionConeArticle
