Graphs of Linear Type

Giovanni Molica Bisci, Maurizio Imbesi

Abstract


There are several papers in graphs theory where are studied algebraic properties of a simple graph . If is the polynomial ring over a field of characteristic zero, is said of linear type if the symmetric and the Rees algebra of its edge ideal over are coincident. A class of graphs of linear type are the Cohen-Macaulay graphs with no even cycles and vertex covering number 3. The above graphs have good properties and a classification of them can be see in [1].
