By generalizing the Zakharov's theory f'or collapses of Langnatuir waves, we investigate theinstabilities of wavefunctions in the 71)-diunensional N-conaponent covrpled nonlinear Schr6dingereqtnations trnder hartaaonic potentials. We show that all waveftrnctions strrely collapse in a finitetinue, when the total energy is negative. For a special case that D : 2 and all coefficients of'harnaonic potential terttas are eqttal, we predict that the collapse can occtmr even when some fieldsinteract reptrlsively.
