   K. R. Parthasarathy is a professor emeritus of graph theory from the Department of Mathematics, Indian Institute of Technology Madras, Chennai. He received his Ph.D. (1966) in graph theory [1] from the Indian Institute of Technology Kharagpur. Parthasarathy is known for his work (with his student G. Ravindra) proving the special case of the ...

3. Graph theory - Wikipedia

   en.wikipedia.org/wiki/Graph_theory

   A drawing of a graph. In 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 arcs, links or lines ).

   In order to do so, it covers several other significant topics in graph theory, number theory, and group theory. It was written by Giuliana Davidoff, Peter Sarnak, and Alain Valette, and published in 2003 by the Cambridge University Press, as volume 55 of the London Mathematical Society Student Texts book series.

5. Algebraic graph theory - Wikipedia

   en.wikipedia.org/wiki/Algebraic_graph_theory

   Algebraic 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 .

7. Spectral graph theory - Wikipedia

   en.wikipedia.org/wiki/Spectral_graph_theory

   Spectral graph theory. In mathematics, spectral graph theory is the study of the properties of a graph in relationship to the characteristic polynomial, eigenvalues, and eigenvectors of matrices associated with the graph, such as its adjacency matrix or Laplacian matrix . The adjacency matrix of a simple undirected graph is a real symmetric ...
