This paper studies the stability of the solution x 0 for a class of quasilinear implicit dynamic equations on time scales of the form AtxÁ f t x . We deal with an index concept to study the solvability and use Lyapunov functions as a tool to approach the stability problem. 1. Introduction The stability theory of quasilinear differential-algebraic equations DAEs for short Atx t f t x t x t f t 0 0 0 vt eR with A. being a given m X m-matrix function has been an intensively discussed field in both theory and practice. This problem can be seen in many real problems such as in electric circuits chemical reactions and vehicle systems. Marz in 1 has dealt with the question whether the zero-solution of is asymptotically stable in the Lyapunov sense with f t x t x t Bx f g t x f x ff with A being constant and small perturbation g. Together with the theory of DAEs there has been a great interest in singular difference equation SDE also referred to as descriptor systems implicit difference equations Anx n 1 f n x n 1 x n n Si. 2 Journal of Inequalities and Applications This model appears in many .
