On r-noncommuting graph of finite rings

Rajat Kanti Nath, Monalisha Sharma, Parama Dutta +1

Let $R$ be a finite ring and $r \in R$ . The $r$ -noncommuting graph of $R$ , denoted by $Γ_{R}^{r}$ , is a simple undirected graph whose vertex set is $R$ and two vertices $x$ and $y$ are…

On Deficient Perfect Numbers with Four Distinct Prime Factors

Parama Dutta, Manjil P. Saikia

For a positive integer $n$ , if $σ (n)$ denotes the sum of the positive divisors of $n$ , then $n$ is called a deficient perfect number if $σ (n) = 2 n - d$ for some positive divisor $d$ of…
