| + | |
- | | + | |
- | * 01.04.2010. Mathieu Dutour: Space fullerenes: computer search for new Frank-Kasper structures
| + | |
- | | + | |
- | Abstract: ''A Frank-Kasper structure is a 3-periodic tiling of the
| + | |
- | Euclidean space E^3 by tetrahedra such that the vertex figure of any
| + | |
- | vertex belongs to 4 specified patterns with, respectively, 20, 24, 26, 28 faces.
| + | |
- | Those polyhedra correspond to fullerenes with isolated hexagons.
| + | |
- | Frank-Kasper structures occur in the crystallography of metallic
| + | |
- | alloys and clathrates but also in the solution of Kelvin's conjecture.
| + | |
- | | + | |
- | A new computer enumeration method has been devised for obtaining
| + | |
- | Frank-Kasper structures up to 20 cells in a reduced fundamental
| + | |
- | domain. The method decomposes in two parts: one combinatorial of
| + | |
- | enumeration of possibilities. Another topological of recognition of
| + | |
- | the structure by the use of Delaney symbols and the program 3dt.
| + | |
- | We compared the 84 obtained structure with the known 27 physical
| + | |
- | structures and the known special constructions by Deza-Shtogrin,
| + | |
- | Sadoc-Mossieri, Frank-Kasper-Sullivan and Shoemaker-Shoemaker.''

- | * 18.03.2010. Mathieu Dutour: Covering maxima and Delaunay polytopes in lattices
| + | |
- | Abstract: ''A family of balls in Euclidean space is called a packing if for
| + | |
- | any two balls B and B' their interior do not self-intersect. It is called
| + | |
- | a covering if every point belong to at least one ball.
| + | |
- | | + | |
- | We focus here on packings and coverings for which the calls are of the form
| + | |
- | x + B(0,R) with x belonging to a lattice L. If L is fixed then we adjust the
| + | |
- | value of R to a value R0 to find the best packing. Alternatively we can
| + | |
- | adjust the value of R to a value R1 to find the best covering. This allow
| + | |
- | us to define the packing density pack(L) and covering density cov(L) of L.
| + | |
- | | + | |
- | The geometry of the function pack on the space of lattices has been
| + | |
- | elucidated by Minkovski, Voronoi and Ash. They showed that the function
| + | |
- | pack has no local minimum, that it is a Morse function and they give
| + | |
- | a characterization of the local maximum in terms of the algebraic notions
| + | |
- | of perfection and eutaxy.
| + | |
- | | + | |
- | The covering function cov is much more complex. It has local minimum and
| + | |
- | local maximum and it is not a Morse function. We also characterize the
| + | |
- | local maximum of the covering density in terms of the corresponding notions
| + | |
- | of perfection and eutaxy this time for Delaunay polytope.''
