Generic Global Rigidity in Complex and Pseudo-Euclidean Spaces, pseudo-Euclidean space (. with a metric of indefinite signature). We show that a graph is generically globally rigid in Euclidean space iff it is generically globally rigid in a complex or pseudo-Euclidean space. We also establish that global rigidity is always a generic property of a graph in comp

Beauville Surfaces and Groups: A Survey,with them. A Beauville surface . is a complex surface formed from two orientably regular hypermaps of genus at least 2 (viewed as compact Riemann surfaces and hence as algebraic curves), with the same automorphism group . acting freely on their product. The following questions are discussed: Which g

More generally, it may be possible to specify the . or similarity class of a geometric regular polytope by means of a fine Schl?fli symbol, whose data contain information abo

Hereditary Polytopes,of polytopes which are called hereditary. Regular polytopes are by definition hereditary, but the other polytopes in this class are interesting, have possible applications in modeling of structures, and have not been previously investigated. This paper establishes the basic theory of hereditary poly
