We describe Laplacian operators on the quantum group SUq (2) equipped with the four-
dimensional bicovariant differential calculus of Woronowicz as well as on the quantum
homogeneous space with the restricted left covariant three-dimensional differential calculus.
This is done by giving a family of Hodge dualities on both the exterior algebras of SUq (2)
and. We also study gauged Laplacian operators acting on sections of line bundles over the
quantum sphere.
