Abstract
The difference of Schrodinger and Dirichlet semigroups is expressed in terms of the Laplace transform of the Brownian motion occupation time . This implies quantitative upper and lower bounds for the operator no rms of the corresponding resolvent differences. One spectral theoretic al consequence is an estimate for the eigenfunction for a Schrodinger operator in a ball where the potential is given as a cone indicates fu nction.
