Graph Theory is a Mathematic field which has many important applications in Informatics and in reality. The basic ideas were proposed by the Swiss Mathematician - Leonhar Euler (1707-1783). He used graphs to solve the famous problem of 7 brigdes in Konigsberg. By using graph models, we can solve many factual problems such as looking for a way to visit an exhibition so that each corridor is passed only once, finding the fewest numbers of colours to colour a map, showing an mutual effects among individuals in a group or a competition among species in natural environment…
There is a close relationship between graph’s features and the invariables in graph. This paper only presents some results of the effects of the former on the relationship among the latter in tree and plane graphs.
