When the target manifold is a Sasakian or cosympletic space form, we characterize invariant immersions, tangential anti-invariant immersions and normal anti-invariant immersions by the spectra of the Jacobi operator.
Keywords: spectral geometry, Jacobi operators, harmonic maps, Sasakian space forms, cosympletic space forms
