Naredni sastanak Seminara Katedre za algebru i matematičku logiku biće održan u petak 1. marta u 13 časova, sala 844.

Predavač: Osama Shafah

Naslov predavanja: On the zero-divisor graph of finite commutative ring.

Sadržaj: This talk is going to be on the zero divisor graph Γ(G) of a finite commutative ring with unity. I will give its definition and some concepts like; The distance between two vertices, the diameter of a graph G, The girth of G, and The meaning of an annihilator. Through some theorems I will give properties of Γ(G).

Also I will mention Zariski topology under the section named as [The spectrum of a commutative ring R], as Iwill give the relation between Gelfand ring and spectrum of R. In the finally talk I will mention cycles in the zero-divisor graph and its connection with a reduced ring R.
