Abstract:
We construct approximate solutions to the time–dependent Schrödinger¶equation
for small values of ħ. If V satisfies appropriate analyticity and growth hypotheses and , these solutions agree with exact solutions up to errors whose norms are bounded by
for some C and γ>0. Under more restrictive hypotheses, we prove that for sufficiently small T ′, implies the norms of the errors are bounded by
for some C ′, γ′>0, and σ > 0.
