Mimar Sinan Güzel Sanatlar Üniversitesi Matematik Bölümü SeminerleriInteresting examples of bipartite divisor graphs of finite groups Roghayeh Hafizieh
Let $G$ be a non-abelian finite group, $cs(G) = \{|x^G| : x \in G\}$ and
let $\rho(G)$ be the set of all primes dividing the elements in $cs(G)$. The bipartite
divisor graph of $G$ is a bipartite graph with $\rho(G)\bigcup cs(G)\setminus\{1\}$
as its vertex
set, such that a prime from $\rho(G)$ like $p$ is joined to an element of $cs(G)\setminus\{1\}$
like $x$ iff $p$ divides $x$.
In this talk we will discuss some properties of this graph and we will give some interesting examples
