On the radius and the relation between the total graph of a commutative ring and its extensions
(Srpska akademija nauka i umetnosti SANU - Matematički institut, Beograd, 2011)
We discuss the determination of the radius of the total graph of a commutative ring R in the case when this graph is connected. Typical extensions such as polynomial rings, formal power series, idealization of the R-module ...
The total graph of a module
(Društvo matematičara Srbije, Beograd, 2011)
A generalization of the total graph of a ring is presented. Various properties are proved and some relations to the total graph of a ring as well as to the zero-divisor graph are established.
