Graph theory graph
WebAlgebraic graph theory is a branch of mathematics in which algebraic methods are applied to problems about graphs. This is in contrast to geometric, combinatoric, or algorithmic approaches. There are three main branches of algebraic graph theory, involving the use of linear algebra, the use of group theory, and the study of graph invariants . WebIn mathematics, graph theory is the study of graphs, which are mathematical structures used to model pairwise relations between objects.A graph in this context is made up of vertices (also called nodes or points) which are connected by edges (also called links or lines).A distinction is made between undirected graphs, where edges link two vertices …
