Coloring Algorithms for Graphs and Hypergraphs with Forbidden Substructures
(University of Waterloo, 2022-04-18)This thesis mainly focus on complexity results of the generalized version of the $r$-Coloring Problem, the $r$-Pre-Coloring Extension Problem and the List $r$-Coloring Problem restricted to hypergraphs and ordered graphs ... -
Cycles and coloring in graphs and digraphs
(University of Waterloo, 2022-08-22)We show results in areas related to extremal problems in directed graphs. The first concerns a rainbow generalization of the Caccetta-H\"{a}ggkvist conjecture, made by Aharoni. The Caccetta-H\"{a}ggkvist conjecture states ...
