= Projective representation
{wiki=Projective_representation}
A projective representation is an extension of the concept of a group representation, which is commonly used in mathematics and theoretical physics. In a standard group representation, a group \\( G \\) acts on a vector space \\( V \\) through linear transformations that preserve the vector space structure. Specifically, for a group representation, there is a homomorphism from the group \\( G \\) into the general linear group \\( GL(V) \\) of the vector space.
