The low-lying excitations of coreless vortex states in F=1 spinor Bose-Einstein condensates BECs are theoretically investigated using the Gross-Pitaevskii and Bogoliubov–de Gennes equations. The spectra of the elementary excitations are calculated for different spin-spin interaction parameters and ratios of the number of particles in each sublevel.
