Projective representation: Projective representations of Lie groups, Linear representations and projective representations & Overview

In the field of representation theory in mathematics, a projective representation of a group G on a vector space V over a field F is a group homomorphism from G to the projective linear group P G L ( V ) = G L ( V ) / F ∗ , {\displaystyle \mathrm {PGL} (V)=\mathrm {GL} (V)/F^{*},} where GL(V) is the general linear group of invertible linear…
