The rapidly expanding area of algebraic graph theory uses two different branches of algebra to explore various aspects of graph theory: linear algebra (for spectral theory) and group theory (for studying graph symmetry). Other books cover portions of this material, but none of these have such a wide scope. CONDITION â USED: Books sold are in GOOD or better condition.
