Yampei L. Algebraic Elements of Graphs 2017 torrent

Textbook in PDF format

This book studies algebraic representations of graphs in order to investigate combinatorial structures via local symmetries. Topological, combinatorial and algebraic classifications are distinguished by invariants of polynomial type and algorithms are designed to determine all such classifications with complexity analysis. Being a summary of the author´s original work on graph embeddings, this book is an essential reference for researchers in graph theory.
