Abstract
The far infrared longitudinal spin and density responses of two-dimensional quantum dots are discussed within local spin-density functional theory. Th e influence of a partial spin polarization, induced by a perpendicular stat ic magnetic field, is taken into account in the coupling of spin and densit y channels. As an illustrative application, the case of a dot made of 5 ele ctrons in parabolic confinement is discussed.
