1. BOOLEAN OPERATIONS WITH COMPOUND SOLIDS REPRESENTED BY BOUNDARY / OPERAÇÕES BOOLEANAS COM SÓLIDOS COMPOSTOS REPRESENTADOS POR FRONTEIRA
Num modelador de sólidos, uma das ferramentas mais poderosas para a criação de objetos tridimensionais de qualquer nível de complexidade geométrica é a aplicação das operações booleanas. Elas são formas intuitivas e populares de combinar sólidos, baseadas nas operações aplicadas a conjuntos. Os tipos principais de operações booleanas comument

2. Visualização automatica de complexos celulares arbitrarios
A two-dimensional cell complex is a partition of a surface into a finite number of elements faces (open discs), edges (open curves) and vertices (points). Here, is described a program which given only the topological structure of a cell complex (that is, the incidence and adjacency relationships between its elements), constructs a geometric representation of

3. Mathematical description of molecular structure: Molecular topology
The concepts of the topology of finite point sets are applied to a mathematical description of molecular structure. The combinatorial properties of the “bond topology,” which arises naturally from atomic adjacency relationships within a molecule, are investigated in detail. The collection of closed sets, the cotopology, is found to be related to bonding.

4. Neutral evolution of mutational robustness
We introduce and analyze a general model of a population evolving over a network of selectively neutral genotypes. We show that the population’s limit distribution on the neutral network is solely determined by the network topology and given by the principal eigenvector of the network’s adjacency matrix. Moreover, the average number of neutral mutant nei
