## Existence theory for nonlinear Volterra integrodifferential and integral equations.(English)Zbl 0891.45004

The authors study parameter identification problems for the nonlinear delay system with state dependent delays $x'(t)= f\Biggl(t,x(t), \int^0_{-r} d_s\mu(s,t,x_t,\sigma) x(t+ s),\theta\Biggr),$ where $$0\leq t\leq T$$, and $$x(t)= \phi(t)$$, $$-r\leq t\leq 0$$. Under assumptions, too complicated to be stated here, an identification method is outlined. Some numerical examples are given.
