Abstract This is the post-doctoral research proposal of Phablo F. S. Moura, to be developed under supervision of professor Flávio K. Miyazawa, at Instituto de Computação of Universidade Estadual de Campinas (UNICAMP).The project lies in the fields of algorithms and graph theory, and focuses on covering and packing problems on graphs. In this project, we plan to investigate the following problems.The first one consists in partitioning (i.e. covering and packing) the set of vertices of a graph in such a way that each part induces a connected subgraph, and all parts are balanced, that is, the weight of the lightest part is maximized. In the second problem, we are interested in covering the set of vertices of a graph with a minimum number of paths.This generalizes the classical Hamilton path problem.The third problem presented in this proposal is related to a long-standing conjecture which deals with finding sufficient conditions for every directed graph to contain, as a subgraph, a subdivision of a given directed graph.
