Unitary representation theory is a branch of mathematics and physics that studies how groups can be represented through unitary operators on Hilbert spaces. In this context, a **unitary representation** of a group \\( G \\) is a homomorphism from the group \\( G \\) into the group of unitary operators on a Hilbert space \\( H \\).
