摘要：

In this paper we establish L-p-boundedness properties for Laplace type transform spectral multipliers associated with the Schrodinger operator L = -Delta + V. We obtain for this type of multipliers pointwise representation as principal value integral operators. We also characterize the UMD Banach spaces in terms of the L-p-boundedness of the imaginary powers,L-i gamma, gamma is an element of R, of L.
