Stability of a linear difference equation and estimation of its fundamental solution
A. Yu. Kulikov, V. V. Malygina Chair of Computational Mathematics and Mechanics, Perm State Technical University, Perm, Russia
Abstract:
We consider a linear nonautonomous system of difference equations. Under natural restrictions we prove that the stability with respect to the initial function and that with respect to the right-hand side in spaces of bounded and summable functions are equivalent to the corresponding estimates for the fundamential solution. As a consequence, we obtain an effective stability condition for a system with a constant matrix.
Keywords:
difference equations, stability, fundamental solution, effective conditions.
