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.
