A combinatorial condition for the existence of polyhedral 2-manifolds

Israel Journal of Mathematics, 1982
LetP denote a polyhedral 2-manifold, i.e. a 2-dimensional cell-complex inRd (d≧3) having convex facets, such that set (P) is homeomorphic to a closed 2-dimensional manifold. LetE be any subset of odd valent vertices ofP, andcE its cardinality. Then for the numbercP(E) of facets containing a vertex ofE the inequality 2cP(E)≧cE+1 is proved.

Polyhedral Mesh Generation and Optimization for Non-manifold Domains

2014
We present a preliminary method to generate polyhedral meshes of general non-manifold domains. The method is based on computing the dual of a general tetrahedral mesh. The resulting mesh respects the topology of the domain to the same extent as the input mesh.

Total absolute curvature of polyhedral manifolds with boundary in E n

Geometriae Dedicata, 1979
N. H. Kuiper has generalized the notion of total absolute curvature for compact polyhedra in euclidean space by considering the critical points of all height functions (cf. [12]). On the other hand in the case of compact smooth manifolds with boundary in En there is a certain relation between the total absolute curvatures of the total space, the ...

Invariant manifold dynamics VIA polyhedral representation

2015
In recent years, manifold dynamics has assumed an increasing relevance for analysis and design of low-energy missions, both in the Earth-Moon system and in alternative multibody environments, and several space missions have already taken advantage of the results of the related studies.
