Abstract

In this dissertation, we explore three problems in the fields of graph theory and combinatorial commutative algebra, and their intersections. First, we prove a higher upper bound for the slow coloring number of a certain class of graphs. Then we provide a novel construction of an old theorem characterizing well-covered bipartite graphs, along with a new proof. Our proof gives more insight into the structure of this class of graphs. Finally, we generate a class of bipartite graphs whose edge ideals are Bi-Cohen-Macaulay, a very strong property that endows these graphs with rich algebraic structure. This work demonstrates the usefulness of viewing the same mathematical
