## Local asymptotic attractivity for nonlinear quadratic functional integral equations.(English)Zbl 1173.47056

The paper deals with the quadratic functional-integral equation of mixed type $x(t)=[f(t,x(\alpha(t)))]\big(q(t)+\int_0^{\beta(t)}g(t,s,x(\gamma(s)))\,ds\big). \tag{1}$ 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 $$\mathbb{R}_+$$.
