Differential representations of driftless discrete-time dynamics
No full textThe paper deals with nonlinear driftless discrete-time dynamics. It is shown that such dynamics can always be represented by an exponential form which corresponds to the solution of a suitable differential equation. This enables us to characterize the associated Lie group structure and to further understand invariance, accessibility and passivity propertie
