NULL STRINGS IN KERR SPACETIME

The null string's equations of motion and constraints in the Kerr spac etime are given. We assume a generic ansatz for the null strings in th e Kerr spacetime and we present the resulting solutions in quadratures . Some specific string configurations, that follow from the generic on e, are considered separately. In each case we also extract the corresp onding solutions in the Schwarzschild spacetime.
