We are investigating the properties of vacuum and boundary states in the CFTof free bosons under the conformal transformation. We show that transformedvacuum (boundary state) is given in terms of tau-functions of dispersionless KP(Toda) hierarchies. Applications of this approach to string field theory isconsidered. We recognize in Neumann coefficients the matrix of secondderivatives of tau-function of dispersionless KP and identify surface stateswith the conformally transformed vacuum of free field theory.Comment: 25 pp, LaTeX, reference added in the Section 3.
