Dhage, Bapurao C.
Local asymptotic attractivity for nonlinear quadratic functional integral equations. (English)
[J] Nonlinear Anal., Theory Methods Appl. 70, No. 5, A, 1912-1922 (2009). ISSN 0362-546X

The paper deals with the quadratic functional-integral equation of mixed type $$ x(t)=[f(t,x(\alpha(t)))]\big(q(t)+\int_0^{\beta(t)}g(t,s,x(\gamma(s)))\,ds\big). \tag1 $$ Using a result about operator equations in Banach algebras, the author proves the existence of a solution of (1) in the space $BC(\mathbb{R}_+,\mathbb{R})$. It is also proved that the solutions of (1) are uniformly locally asymptotically attractive on $\mathbb{R}_+$.
