On the unbounded extendability of solutions to nonlinear differential algebraic equations

A. A. Shcheglova

Institute for System Dynamics and Control Theory, Irkutsk, Russia

Abstract: We consider a system of nonlinear ordinary differential equations that are unsolved for the derivative of the unknown vector function and identically degenerate on the domain. We prove a theorem on the unbounded extendability of solutions to this system, allowing arbitrarily high unsolvability index with respect to the derivative.

Keywords: differential algebraic equations, unbounded extendability of solutions, global structure form.
