Grafos de Cayley

, 2017
Two of the most relevant branches of modern day Mathematics are Group Theory and Graph Theory. Both theories meet in Cayley digraphs. Cayley digraphs are a new way to observe and represent the structure of a group or of a determined set of groups.

Grafos em superfícies

, 2015
The main goal of this work is to get a result on separation of surfaces by graphs. The Relative Homology is the principal tool used and we get a particular version of Lefschetz duality. For the preparation of this dissertation we studied: graphs, simplicial homology, relative homology and graphs on surfaces.

Coloraciones de grafos: grafos planos y polinomio cromático

Coloring a graph means assigning “colors” to its vertices so that two adjacent vertices never have the same color. This is a very classical problem because of its relation to, for example, map colorings and the famous Four Color Theorem, but it also has practical applications, for example when you want to divide a set into groups but there are certain ...

Coloración de grafos

, 2000
Estudiamos algunos resultados sobre rama-coloración de grafos y su relación con el teorema del mapa de cuatro colores. A tal fin, se introduce la noción de “coloración” de una conjunto de ramas y se estudian sus propiedades relacionadas con el álgebra de Boole.

CLUSTERING SU GRAFO

Ratio Mathematica, 1992
The present paper deals with the following problem: given a connected graph G with n nodes, partition its set of nodee into p classes such that the subgraph induced by each class is connected and given function, inertia; of the partition is minimized This paper includes : a heuristic algorithm for general graphs based on the solution of a sequence of ...
