On the Faithful Projective Representations of Finite Groups and their Minimal Dimension

Sumana Hatui, Poonam Nayak

The first part of this article is devoted to characterizing the cocycles $I^\pm$ of a finite group $G$ that give rise to faithful projective representations of $G$ . We prove that a $p…

On Projective Representations of Special p-groups

Sumana Hatui

Let $G$ be a special $p$ -group. If $G$ is of rank two, or $G$ is of maximum rank with $∣ G^{p} ∣ \leq p$ , then we describe the complex irreducible projective representations of $G$ .
