This paper investigates geometrically (Q,S,R)-incremental dissipativity and incremental stability for switched time-varying nonlinear discrete-time systems. A geometrically (Q,S,R)-incremental dissipativity concept is proposed for switched nonlinear discrete-time systems by using multiple storage functions and multiple incremental supply rate. Furthermore, the sufficient conditions of geometrically (Q,S,R)-incremental dissipativity are given under the design of state-dependent switching law. The incremental stability conditions are derived for geometrically (Q,S,R)-incrementally dissipative switched systems. By designing of a composite state-dependent switching law, the feedback interconnected switched systems are ensured to be geometrically (Q,S,R)-incrementally dissipative. A numerical example is given to illustrate the validity of the proposed approach.
