Description
  • The project belongs to the areas of structural and algorithmic graph theory and it aims at providing new knowledge on the structure and the existence of colorings and flows in graphs. The scope of the project also includes problems related to cycles in graphs and matroids and algorithmic applications of the studied objects, in particular, in the areas of the channel assignment problem and the multicommodity flows.The structural problems addressed by the project include the colorings of embedded graphs with constraints given by an embedding (cyclic, facial colorings), the structure of critical and list-critical graphs on surfaces, the Shortest Cycle Cover Conjecture, and circular and fractional relaxations of the known open problems on colorings and flows. The applications include the channel assignment problem, in particular the recently developed framework of real number graph labellings, and algorithms for multiroute and length-bounded flows. (en)
  • Cílem projektu je prohloubit současnou úroveň znalostí o obyčejných, seznamových, cirkulárních a zlomkových obarveních a tocích v grafech, speciálně v grafech vnořených na plochy, o struktuře cyklů v grafech a matroidech, a o algoritmických aplikacích těchto objektů.
