Structural Graph Theory explores the analysis of graphs and their intrinsic characteristics, focusing on vertices, edges, and their interconnections. It encompasses concepts like graph isomorphism, connectivity, and coloring, and includes theorems such as Euler's, Kuratowski's, and Hall's. This field is essential in modeling complex systems for social networks, computer science, transportation, and more, offering insights for efficient network designs and problem-solving.

00
Define graph isomorphism.
Graph isomorphism is the equivalence of graphs, structurally identical in terms of vertex connectivity, regardless of vertex labels or edge order.
01
Explain graph connectivity.
Graph connectivity refers to the minimum number of elements (vertices or edges) that need to be removed to disconnect the remaining vertices from each other.
02
What is graph coloring?
Graph coloring is the assignment of labels (colors) to elements of a graph (vertices, edges, or regions) such that no adjacent elements share the same color, often used to illustrate scheduling or partitioning problems.
