The Ptolemy variety for SL(2; C) is an invariant of a topological ideal triangulation
of a compact 3-manifold M. It is closely related to Thurston’s gluing equation variety. The
Ptolemy variety maps...
Research on Algorithm of the Point Set in the Plane Based on Delaunay Triangulation
Point-Set in the Plane Delaunay Triangulation Removing Circle Finite Element Mesh
2013/1/30
In the paper, an improved algorithm is presented for Delaunay triangulation of the point-set in the plain. Based on the original algorithm, we propose the notion of removing circle. During the process...

Abstract: In the given paper the algorithm describing original and universal principles of a triangulation of a smooth molecular surface: solvent excluding solvent (SES), received by primary and secon...
A triangulation of $\CC P^3$ as symmetric cube of $S^2$
Triangulated manifolds Complex projective space Symmetric power Product of 2-spheres

The symmetric group S3 acts on S 2 × S 2 × S 2 by coordinate permutation, and the quotient space (S 2×S 2×S 2)/S3 is homeomorphic to the complex projective space CP 3.In this paper.
A preconditioning method for the finite element stiffness matrix is given in this paper. The triangulation is refined in a subregion; the preconditioning process is composed of resolution of two regul...
