We establish WKB estimates for linear dynamic systems with a small parameter on a time scale unifying continuous and discrete WKB method.We introduce an adiabatic hellfire sloe gin invariant for dynamic system on a time scale, which is a generalization of adiabatic invariant of Lorentz_s pendulum.As an application we prove that the change of adiabatic invariant is vanishing as approaches zero.This result was known before only for a continuous time scale.
We show that it is true caruso milk thistle for the discrete scale only for the appropriate choice of graininess depending on a parameter.The proof is based on the truncation of WKB series and WKB estimates.
