--- title: "Network Reliability Parameters" date: 2023-12-18T00:21:27-05:00 abstract: > Let $G=(V,E)$ be a finite undirected graph with no isolated vertices. A set $S \subseteq V$ is said to be a total dominating set of $G$ if every vertex in $V$ is adjacent to some vertex in $S$. The total domination number, $\gamma_{t}(G)$, is the minimum cardinality of a total dominating set in $G$. We define the $k$-total bondage to be the minimum number of edges to remove from $G$ so that the resulting graph has a total dominating number at least $k$ more than $\gamma_{t}(G)$. In this work we establish general properties of $k$-total bondage, exact values for certain graph classes including paths, cycles, and wheels, and obtain upper bounds for complete and complete bipartite graphs. summary: "$k$-total bondage of Graphs" description: "Brief Description of Research" math: true categories: - "Moravian REU 2023" tags: - "Graph Theory" - "Combinatorics" --- Peer Researchers : Gabriel Fischberg : Kyle Kelley : Eliel Sosis Mentors : Dr. Nathan Shank {{< presentations >}} ## Presentations * Poster Sessions * [Mathfest 2023](/research/posters/networks_mathfest23.pdf) {{< /presentations >}}
