摘要

In the first part of this paper, we study operators f(H) and e~(-itH)f(H) in L~p(R~d), where H=-Δ+V(x) is a Schroedinger operator defined primarily as a self-ad joint operator in L~2(R~d). For H_0=—Δ, mapping properties of f(H_0) between L~p-spaces and norm estimates for e~(-itH_0) f(H_0) follow from the theory of Fourier multipliers. One of our goals is to extend these results to a fairly large class of Schroedinger operators H=H_0+V(x).
