For a bridge decomposition of a link in the-sphere, we define the Goeritz group to be the group of isotopy classes of orientation-preserving homeomorphisms of the-sphere that preserve each of the bridge sphere and link setwise. After describing basic properties of this group, we discuss the asymptotic behavior of the minimal pseudo-Anosov entropies. We then give an application to the asymptotic behavior of the minimal entropies for the original Goeritz groups of Heegaard splittings of the-sphere and the real projective space.
