โฆ Synopsis
Let H be the three-dimensional hyperbolic space and let G be the identity component of the isometry group of H . It is known that some aspects of the dynamics of a rigid body in H contrast strongly with the Euclidean case, due to the lack of a subgroup of translations in G. We present the subject in the context of homogeneous Riemannian geometry, finding the metrics on G naturally associated with extended rigid bodies in H . We concentrate on the concept of dynamical center, characterizing it in various ways.

This paper examines dynamic response of a type of structural system that exhibits a significant degree of rigid body motion during earthquakes. An assembly of two-dimensional rigid prisms subjected to self-imposed kinematic constraints is chosen as a representative model for this type of structure.
