In this thesis, we are doing to highlight two different relations between graphs and finite commutative rings. The first one is the well known as Unitary Cayley Graph, where the study of this association and some results are presented from (1). The second on is a completely different; it connects digraphs with quadratic polynomials with coeffitients in Zn under the mapping (a,b)-> (a+b,ab), for some n<...... A Computer calculations are involved to support the study. The algorithm which is used for these calculations is built on original Mathematica and Matlab Softwares. Furthemore, Some principles are needed in this thesis for the seek of support and completeness... |
